Waste Utilization for Sustainable Energy Resources 19 December 2018, 10:00-10:30, Arnoma Grand Room II and III
Prof. Dr. Ashwani K. Gupta Department of Mechanical Engineering University of Maryland, College Park, MD 20742, USA
Abstract. Biomass is the only carbon based energy source that can provide sustainable replacement for fossil fuel based energy production. While different thermochemical routes are available for biomass utilization, understanding the reaction pathway and the influence of its individual components and structure is essential for efficient and effective utilization of product selective biomass. Cellulose is the most common component in biomass feedstocks. Pyrolysis and gasification of cellulose and biomass will be presented for clean syngas production and converting char to activated char. In-situ diffuse reflectance Fourier-transform infrared spectroscopy (DRIFTS) was used to understand the evolution of surface functional groups with increase in temperature. The evolution of infrared (IR) bands with increase in temperature that corresponded to different functional groups provided insights into the intermediates formed for both volatile evolution and charring reaction during pyrolysis, which provided supportive evidence on the reaction pathways during pyrolysis of cellulose and potentially also other various biomass feedstocks. The research on CO2 conversion to CO and its further conversion to products, such as methanol and ethylene will also be directed. The endothermic conversion of CO2 to CO requires thermal energy, which can be simulated in lab scale environment using a thermal rector but in real application it can be supplied from renewable thermal energy such as solar, geothermal or waste heat sources. Catalytic thermochemical looping involving redox reactions of advanced metal oxides can be developed for converting CO2 to CO via thermal splitting. Experimental investigation into multiple mixed metal oxides for efficient oxygen carrier design to obtain high temperature resilience and high selectivity for CO production will be discussed. The effect of steam addition to CO2 to produce a mixture of H2-rich mixture of CO and H2 will be highlighted. Mixtures of CO and H2 are key components for the production of essential petrochemical intermediates, such as methanol. Experimental results on methanol production from CO and H2 will be compared with CO2 and H2 mixtures route for seeking efficient production under different upstream conditions. Experimental evaluation into value added intermediates, such as ethylene, (and propylene) production will be via methanol dehydration and compared with production via Fischer-Tropsch synthesis route in order to
6
obtain compatible pathway for olefin production from CO2. These evaluations can help assist in providing an efficient, sustainable and carbon negative pathway of using CO2 to marketable products, such as, methanol and ethylene, and potentially polymers and plastics.

Dioxins in Waste Incineration – from Problem to Solution 19 December 2018, 11:00-11:30, Arnoma Grand Room II and III
Dr. Juergen Vehlow Karlsruhe Institute of Technology, retired
Abstract. In 1977 Olie, Vermeulen, and Hutzinger were the first to detect dioxins in fly ashes from waste incineration plants. The toxicity of these compounds was known, but not their source in the process. Hence violent discussions and with that strong public opposition against waste incineration emerged in many countries. But at the same time extended research and development programs were launched to understand the formation of these compounds and revealed in short time their main formation mechanisms by identifying the most important operation parameters (good combustion control, clean boilers) and the influence of specific waste ingredients (halogens, sulphur, some heavy metals) controlling their generation. This acquired knowledge paved the way for strategies to minimise their formation and to achieve an efficient abatement. The main steps in this development as well as the current situation are described.

Accomplishment and perspectives on the international cooperation in new climate change era 19 December 2018, 11:30-12:00, Arnoma Grand Room II and III
Jongsoo Jurng Director General, Green Technology Center of Korea
Abstract. The Green Technology Center ( GTC) of Korea, established in 2013 as a policy research center specializing in green climate technology, has been fulfilling its primary role of researching green technology development policy and international cooperation on climate technology. Following the 2015 Paris Agreement, increased importance has been placed on policy and international cooperation for climate change technology transfer. In Korea, climate change technology has emerged as a means of reducing greenhouse gas emissions and has been magnified as a core technology for the resolution of various social problems, too. In order to actively address national and global environmental issues, GTC is making great efforts to lead on new innovations and challenges by reflecting paradigm transformation for the realization of the creative economy. This lays the groundwork to pass down a healthy and sustainable environment for future generations. By strengthening global leadership through the establishment of a Korean climate technology cooperation model, the GTC is making efforts for the global expansion of domestic climate technology industries as well as for the establishment of and progress towards domestic greenhouse gas emission reduction goals. Waste-to-Energy is one of the main agenda that GTC has explored in perspective of an effective solution for climate change mitigation. GTC has supported the technical assistance on policy development and feasibility study, capacity building program, and demonstration and its performance evaluation. Under the framework of sustainable solid waste management, the practical approaches to applying the waste- to-energy solutions have been investigated with respect to their social, environmental and economic impacts Biography 2018. 4 – Present Director General, Green Technology Center of Korea 2011. 9 - Present Professor (adj.), Green School, KIST-Korea Univ. 2011. 3 - Present Principal Research Scientist, Green City Technology Institute, KIST 2013 Visiting Scholar, Univ. of Texas, Austin, USA 2010. 4 - 2013. 4 Expert Committee member, National Science and Technology Commission 2009.11 - 2011.3 Director, Environment Division, KIST 2005.5 - 2009.11 Head, Center for Environmental Technology Research, KIST 2003.11 - 2005.5: Policy Analyst, the Office of the Prime Minster, Korea Field of Interest: Green Technology, Control Technology for Air Pollutants and Hazardous Substances, Environmental Catalyst, Indoor Air Quality, Environmental Sensors, Waste Incineration

High Quality Solid Fuel Production from Biomass and Wastes Employing the Hydrothermal Treatment 19 December 2018, 12:00-12:30, Arnoma Grand Room II and III
Kunio Yoshikawa Tokyo Institute of Technology
Abstract. Up to now, the only commercialized ways of municipal solid waste (MSW) treatment are mass land-filling and mass burning. In Japan, most of burnable wastes are incinerated, but not in other countries, and still land-filling is the most popular way of waste treatment all over the world. But the world recent trend is to prohibit or limit land-filling of wastes while citizens do not want to increase waste incineration in developed countries as well as developing countries. On the other hand, major part of the world is discharging non-segregated municipal solid wastes. Thus we have to find out the utilization ways alternative to incineration for non-segregated MSW. Pre-treatment of wastes requires crushing, drying and deodorizing, which are normally different processes. But we have developed innovative hydrothermal treatment technology (HTT) which can perform these three pre-treatment functions in one process utilizing high pressure saturated steam. Figure 1 shows the operating principle of HTT. Non-segregated MSW are fed into the reactor, and then, 220�, 2.5MPa saturated steam is supplied into the reactor for about 30 minutes and the blades installed inside the reactor rotates to mix MSW and steam for about 10 minutes. Then the product is discharged after extracting steam. The product is powder-like substance and the moisture content is almost the same as the raw material, but is easily dried by natural drying. The inert material such as metal, glass and stones can be easily sieved out after drying. There is almost no bad smell in the solid products, and the products can be used as solid fuels which can be easily mixed with coal for power generation or cement production. Only 10-15% of the product is enough for steam production in a boiler. HTT has already commercialized in Japan, China and Indonesia. Biography Prof. Kunio Yoshikawa was born in 1953 in Tokyo, Japan. He is a professor of Tokyo Institute of Technology and an associate editor of Applied Energy. His bachelor, master and doctor degrees were awarded from Tokyo Institute of Technology.

Technological Status and Issues on Waste to Energy in Korea and Asian Countries 18 December 2018, 15:20-15:50, Arnoma Grand Room III
Prof. Yong-Chil Seo Yonsei University, Republic of Korea
Abstract. The generation and management of waste in Asian countries are varying by each country’s situation, and so are the statuses of waste to energy (WtE) as well. Korean history of waste management and WtE utilization are going to be discussed and the other countries which have been actively adopted and going to utilize WtE technologies will also be introduced comparatively. Two times of WtE policies and utilization strategies would make the rate of WtE up to 20% among total municipal solid waste (MSW) generated in Korea. Of course it has played very significant role for effective waste management in integrated manner. Japan already adopted WtE plants long years ago, while China has constructed most of incinerators recent years, which currently reaches more than 300 large scale plants for MSWs. Other Asian countries may be in the situation to start to consider or construct MSW WtE plants. These developing countries may learn from such utilization histories of WtE adoption in Japan, Korea and China. Not only combustion technology but also advanced technologies such as gasification, solid refuse fuel (SRF), and bio-gas production for organic waste, are also to be future and present options as WtE technologies. To give insights and future investigations, several R&Ds performed recently and collaboration efforts for developing technologies are going to be introduced in the lecture.

Abstract:
The combustion characteristics of lean non-premixed Thai synthetic natural gas combustion on
improved inverse diffusion flame (IDF) burner was investigated. Air and fuel nozzles were improved
from normal diffusion flame burner (NDF) and set as inside and outside exits on burner, respectively.
The combustion flames were studied with decrease of fuel flow rate and increase of air flow rate as lean
combustion system. The luminous flame length was lower and premixed flame length was higher by
designed IDF burner due to enhance of mixing between inside air and ambient air. When the equivalence
ratio decreased, lower flame length, flame temperature, light emission, low emission of CO and NOx
were obtained. Moreover, the highest premixed combustion flames and the maximum temperature were
observed at Φ=0.76-0.80 on lean non-premixed synthetic Thai natural gas flames with designed IDF
burner.

Abstract:
.Recently, the use of fluidized bed reactors has been proposed for production of high purity rare metals such as molybdenum trioxides and metal compounds, such as iron oxides, fullerene like WS2. In this work, a novel two-stage reduction process for production of high purity nickel power and low density in a fluidized bed reactor has been developed. The low grade NiO powder has a bulk density of 4.1 g/cm3 and a particle size below 10mm. All of the experiments were performed in the two stage fluidized bed hydrogen reactor. For the experiment of two stage fluidized bed hydrogen reduction, the NiO power were pre-reduced at temperature range from 450 to 550oC for approximately 30 min in the first stage reactor, followed by second reduction at temperature range from 600 to 650oC for 30 min in the second stage reactor. After the second reaction, Ni particles were moved to the fluidized bed cooling reactor which was cooled to room temperature by N2 gas before the products were obtained and sealed. The phase structures of the products were analyzed using X-ray diffractometry (XRD, X-Pert MPD Pro.) with Cu Ka radiation at 40kV and 40mA. The microstructure analysis of the powder was conducted using a field emission scanning electron microscope (FESEM, JSM-7001F) equipped with an energy dispersive X-ray spectroscopy (EDS) detector (INCA X-Max). The low grade NiO particles are first pre-reduced using hydrogen at proper temperature (550oC), followed by further reduction at higher temperature (600-650oC). The self-agglomeration of Ni particles formed during low temperature reduction below at 500oC in first stage reactor decreases the sintering activity of the newly formed Ni particles, leading to poor fluidization quality, even for the subsequent high temperature reduction process. But, the self-agglomeration of Ni particles did not formed high reduction temperature at 650oC in the second stage reactor. They were leading to good fluidization quality. The reduced Ni particle have a high Ni content above 99.57 wt.%, a low density of 0.78 g/cm3 and a uniform particle size approximately 100mm. A concept of the business model for a novel two stage fluidized bed hydrogen reaction process to produce high purity Ni powder was also proposed.

The use of biomass as carbon-neutral fuel for power generation has been increasing rapidly to displace the fossil fuels. It also has advantages of diversifying the fuel portfolio in a power plant and of reducing SO2 and NOx emissions. One common method for using biomass is to co-firing in existing boilers. NOx is one of the main gas-phase pollutants released by oxidation of fuel-bound N and N2. For solid fuels such as coal and biomass, the fuel NOx formation is dominant over that for the thermal NOx. Although NOx released from the furnace can be removed by flue gas cleaning, it is required to minimize the NOx formation during combustion for lower operational costs. The present study aims to investigate the contribution of biomass to reducing NOx emission by direct co-firing with fossil fuels. For this purpose, various biomass types were tested in a bench-scale furnace using coal as the main fuel. The effects of key combustible species in the various biomass on NOx reductions were evaluated quantitatively based on detailed measurement within the furnaces. When biomass was directed co-fired with the main fuel, NOx emission decreased as co-firing ratios increased mainly due to the low fuel N contents of various biomass types. Among tested biomass types, wood pellets and empty fruit bunch were found suitable for co-firing fuel due to good grindability and low fuel N content.

Abstract: The advent of the automobile industry coupled with great strides in economic growth, triggered the large
production of tires from both natural and synthetic rubber, consequently large volumes of end of life tire
is generated only to meet inadequate tire disposal systems. Traditionally, waste tires are disposed of in
landfills or simply uncontrolled burning, both of which exacerbate an already dire environmental
concern, the former consumes more volume than most waste and contributes to the shortening of landfill
life while the later disperses particulate matter and noxious gases into the atmosphere and fails to harness
potential heat energy. In keeping with green waste management policies, thermal disposal methods such
as incineration, pyrolysis and gasification have received much attention. Chief among the advantages of
these technologies is the ability to recover tire components from pyrolysis or gasification and energy
harvesting form incineration while posing little to no harm to the environment. The main aim of this
work is to assess the feasibility of co-gasification of waste tire with coal in already existing plants as a
cost effective way of tire disposal. However the heterogeneity of the tire begs the question whether or
not it is effective to separate the tire prior gasification.
This work reports the kinetic analysis of CO2 gasification reactions for distinct tire components namely
tire tread (TT) and sidewall (SW) for chars produced at 450 C in a bid to justify separation of waste tire
before gasification. Elemental analysis of TT and SW show that the former contains 17.86% of ash while
the later has 7.41%, consequently SW contains 12.19% more carbon. The isothermal thermogravimetic
analysis at atmospheric pressure was carried out within the temperature range of 825-1100 C, where the
onset of the diffusion control is 925 C for both samples. The random pore model described the data well
compared to the volumetric and grain models. Intrinsic kinetic parameters were determined: the
activation energy ranging from 115-137 kJ/mol for tire-tread and 124-149 kJ/mol for sidewall, the lower
32
values for tire tread maybe due to the catalytic effect of the ash components. Complementary to
determining the onset of the diffusion control by use of the Arrhenius plot, this paper also reports that
tracking the magnitude of the structural parameter as defined by the random pore model is applicable in
this regard. It was observed that when the reaction regime changes the parameter’s magnitude changes
drastically. The conversion-time relationships of sidewall and tire tread are distinct; the sidewall
relationship is nearly linear with no inhibition effect even at a high conversion. When the conversion-
time relationships are superimposed, the graphs are nearly coincident until the conversion of 0.73 for
temperatures lower than 925 C, and thereafter, tire-tread diverges due to the high ash content. This
suggests that the sidewall and tire tread are composed of the same type of rubber and the difference in
the reactivity at a higher conversion is due to the inhibition effect caused by the high ash content of tire
tread. Consequently, tire tread has a longer reaction time compared to sidewall.
The sidewall and tire tread chars were blended with bituminous coal (BC) at 50 % and 75% bituminous
coal proportion and gasified at temperatures of 850, 900 and 950 . It was observed that the tire char
reactivity was enhanced by increasing the coal proportion as well as increasing the temperature. At all
temperatures, the isothermal CO2 gasification reactivity followed the trend: BC>BC:
SW_3:1 BC:TT_3:1>BC: SW_1:1>BC: TT_1:1. The reactivity index was similar for TT and SW but
lower in the magnitude compared to bituminous coal. It was concluded that the reactivity is enhanced
by increasing the coal proportion and decreasing the gasification temperature. At 850 C, all blends
exhibited synergy, however at higher temperatures, there exists no interaction and inhibition effect for
most of the reaction at conversions lower than 60% and synergy is apparent at greater conversions. This
may be due to the catalytic behavior of remaining Ca2+ ion which increases as the carbon is depleted
during the course of the reaction. For all blends it was observed that synergy decreased with an increase
in the temperature albeit relatively small changes of the order of not more than 0.1. At higher
temperatures inherent alkaline earth metals react with inert SiO2 and Al2O3 thus deactivating their
catalytic effect hence decreasing synergistic effects. From the aforementioned discussion, it can be
concluded that it is not necessary to separate waste tire prior to gasification given the similar reactivity
of tire tread and sidewall.

Abstract:
The tremendous amount of food waste is generated throughout the globe, posing a challenge for
its management. Food waste as a biomass resource is recently recognized to have great potential for
chemical and energy recovery. One of the promising technologies for energy generation from biomass
is gasification whose operation is inhibited, in both technical and economic aspects, by the moisture
content of food waste. Therefore, a pre-treatment process of food waste is a requisite before subjecting
the waste to a gasification reactor. Two promising pre-treatments able to improve biomass properties are
carbonization (CB) and hydrothermal carbonization (HTC). However, the suitability of the methods
highly depends on the characteristics of feed stock. For food waste, the suitable method was not yet
determined and there has not been any reports on the comparison of these two methods with regards to
the gasification performance. Owing to the lack of the aforementioned study, a comparative study of
gasification behaviour of chars produced from the different two pre-treatments should be conducted. The
main objective of this research is to investigate and compare the yield, the properties and the gasification
reactivity of food waste chars derived from two different pre-treatment processes. Moreover, an effect
of the process temperature in both methods on those food waste chars was also tested.
Raw cabbage and chicken meat, bought from a supermarket, were used as representatives for
vegetable-type and high-protein fractions of food waste respectively. Both samples were initially dried
and hydrothermally carbonized under the temperature of 180, 200 and 220 °C for 30 minutes with the
feedstock-to-water ratio of 1:5. For the pyrolytic carbonization, the raw samples were pyrolized under
the temperature of 300, 350, 400 and 450 °C for 1 hour. The proximate and ultimate analyses of the raw
samples and the char products were then conducted. Some amounts of each char sample were further
34
pyrolized at the temperature of 900 °C for 1 hour in order to produce samples for Thermal Gravity
Analysis (TGA) to determine the gasification reactivity of the samples.
Compared to hydrochars, carbonized chars had a lower volatile matter (VM) content but showed
higher carbon and ash contents. The fraction of VM of cabbage hydrochars and all carbonized chars
dropped significantly with an increase in the process temperature. However, the increase in VM of
chicken hydrochars, from 86 to 94 %, might be due to the hydrolysis of protein, leaving more lipid in the
chicken hydrochars as the temperature increased. The oxygen content of carbonized chars were lower
than that of hydrochars due to the higher process temperature but both chars showed the reduction in the
O content. They also displayed lower N contents compared to raw feedstock. Especially, the chicken
hydrochars showed more significant decrease in the N content from 11.0 to 6.5 % as the temperature
increased. This phenomena may be due to easier hydrolysis reaction of protein at a lower temperature
compared sugar polymers. The cabbage hydrochars are in comparison with lignite with the H/C and O/C
ratio reduction up to 1.01 and 0.33 respectively and the cabbage carbonized chars are even close to the
sub-bituminous region with the H/C and O/C ratio reduction up to 0.64 and 0.07 respectively. The
productivity of the chicken hydrochars was very low with only 22.5 and 8.0 % at 180 and 200°C
respectively. From the TGA result, hydrochars demonstrated a lower gasification activity. This could be
the consequence of the reduction of catalyst in char samples after the HTC process. During HTC, some
of the alkaline salt which could act as catalyst would be dissolved into liquid phase while it still remained
in carbonized chars. This was also attributed to a lower ash content in HTT chars than CB chars as shown
in the proximate analysis.
In conclusion, higher VM can be seen in hydrochars. However, hydrochars presented the
reduction of both oxygen and ash contents while only that of oxygen can be seen in carbonized chars.
The nitrogen content can also be significantly reduced by HTC, especially for highly nitrogen-containing
feed stock. Hydrochars clearly showed lower reactivity compared to carbonized chars due to the loss of
catalyst during the HTC process. To determine the best pre-treatment method for food waste, information
from further study such as the syngas analysis and the tar concentration should be acquired.

Abstract:
Biomass waste is a renewable sources and its effective utilization is indispensable, particularly in
Thailand, where massive amounts of biomass wastes are generated. Moreover, charcoal from biomass
wastes is regarded as candidates for low priced raw materials for activated carbons. However, the yield
of charcoal from biomass wastes is low in general. So, it is essential to develop a method to increase the
yield of charcoal during the carbonization of biomass wastes. In this study, Leucaena, which is a woody
biomass, was pressurized at around 500 MPa at room temperature, called cold press in this work, to
prepare biomass pellet. Leucaena was also pre-carbonized under the mechanical pressure of around 10
MPa at the temperature range of 25 oC to around 250 oC, called hot press in this work, to prepare densified
semi-chars. Then, both cold press pellets and hot press semi-chars were subjected to carbonization at
around 900 oC. It was found that the char yield of cold press pellets prepared from leucaena was 21.9
wt%, while the char yield of powder leucaena was only 17.0 wt%. On the other hand, the char yield of hot
press semi-char prepared from leucaena was surprisingly increased to 27.7 wt%. From the detail analyses
of gas formation during the carbonization, it was found that the dehydration reaction was accelerated by
hot press carbonization and the mechanical pressure suppresses the evolution of tar components.
Therefore, the mechanical pressure is judged to be effective to increase the char yield through the
carbonization of biomass.

Abstract: The utilization of phosphorus in sewage sludge is an important method to solve the shortage of
phosphorus resources in the world. High levels of toxic compounds and low phosphorus bioavailability
in sewage sludge are main factors limiting its direct agricultural use. This study proposes a low-
temperature combustion method, which can enrich phosphorus in sludge slag. Low-temperature treated
sewage sludge slag (LTSS) at different oxygen concentrations (20%, 60%, 100%) were obtained through a
specific experimental device, then the species and leaching characteristics of phosphorus in LTSSs were
analyzed, further, compared with pyrolysis sewage sludge char (PSSC) and incinerated sewage sludge
slag (ISSS). The results indicate that low-temperature combustion of sludge increased total phosphorus
content in slag by 45.6% and bioavailable phosphorus content increased by 2.9-fold. In addition,
increasing oxygen concentration during the process of low-temperature combustion can convert non-
apatite inorganic P to apatite P (AP) in sludge, make the content of AP increased by 46.3%. Low-
temperature combustion can also convert heavy metals (Cd, Cr, Cu, Pb, and Zn) in the sludge from easy
leachable form (acid extractable fraction and reducible fraction) to stable form (reducible fraction) and
decrease leaching toxicity of heavy metal. Leaching toxicity of Cr and Cu decreased by 97.56% and
98.52%.

Abstract:
Rice husk is one of the most widely available agriculture residues. It was a promising eco-friendly
alternative source of renewable energy in the context of current energy scenarios. Fast pyrolysis
technologies can transform rice husk into bio-oil considering its physical and chemical properties.
Catalytic pyrolysis experiments have been carried out on Japanese rice husk to obtain bio-oil using a
fixed-bed pyrolysis reactor with the use of the catalyst and comparison was done to analyze the changes
in the bio-oil properties and yield. The fast pyrolysis of rice husk has been performed in the temperature
range of 400-600 °C using the experimental pyrolysis reactor. The correlation between the temperature
and the product yield shows the highest product yield at 450 °C. Properties of the liquid catalytic and
non-catalytic bio-oils were analyzed in terms of the water content, pH, the acid number, the viscosity,
the density and the calorific value.
The objective of this research is to explore the possibility to upgrade bio-oil produced from
rice husk using a bench-scale fixed bed reactor with two heating units employing the cracking method.
The catalytic cracking is the most promising bio-oil upgrading processes, and it can remove oxygenated
compounds from bio-oil via H2O, CO and CO2. The catalyst was HZSM-5 zeolite, which is commonly
used in bio-oil upgrading by the cracking. This catalyst was compared with other non-commercial
catalysts such as rice husk ash to reduce cost. The result showed that by using two heating units, even
without catalyst, the upgrading was achieved well. The catalytic cracking promoted the deoxygenation
rate and further improved the quality of the upgraded oil compared with the non-catalytic cracking case.
By separating two heating units with different operating temperatures, the catalytic effect and the
41
deactivation of the catalyst was clarified. The raw rice husk bio-oil produced and the upgraded bio-oil
were characterized by measuring their element content, water content and the chemical composition of
its organic fraction.
The implementation of the pyrolysis cracking method in a bench-scale reactor with two heating
units produced upgraded oil and saved the catalyst. The temperature of each unit was independently
controlled using the temperature controllers respectively. The main point of this process is the use of
different temperatures for each heating unit. In this way, the upgraded oil has equal quality as the one
upgraded by other chemical methods. The catalysts used were HZSM-5 zeolite and rice husk ash which
were appropriately effective in the bio-oil crack upgrading. The model compounds were chosen to verify
the reaction principle.

Therefore, in this study, these SRF residues were tried to be treated in appropriate manner by applied
a thermal technology. Hence the incineration experiments were carried out after the mechanical
biological treatment of the residues to upgrade the quality of them. Mechanical treatment consisted of
shredding, particle size separation, wind force separation, gravity separation, magnetic separation, and
optical sorting. Biological treatment processes included aerobic and anaerobic treatment. In the case of
bio-drying, a part of aerobic treatment, was associated. Conditions of the incineration process were as
follows: air ratio of 2.3 and feeding rate is 12 kg/hr. Also bottom ash generated after incineration used to
be buried. However, in this study, we could be recycling bottom ash by manufacturing bricks. The
variation of bottom ash properties influenced the characteristics of bricks and also it could be hazardous
for environment. So, before manufacturing bricks for bottom ash, basic characteristic of bottom ash such
43
as ignition loss and heavy metal leaching test must be analyzed. The concentration of chlorine
compounds in the bottom ash was slightly higher at 3,500 ppm. This was known to cause manufacturing
process problems as it was accumulated in the cyclone during the cement manufacturing process or
coated in the preheating, so chlorine concentration did not exceed 1,000 ppm in the cement
manufacturing process. Therefore, hydrothermal treatment experiments were introduced to make lower
the chlorine concentration and utilize it as raw material for cement. The hydrothermal treatment method
was a method of proceeding decomposition and carbonization of organic materials by using the
subcritical water under high temperature and high pressure. At a high pressure and a certain high
temperature, the cell walls of the microorganisms are destroyed by steam, and the viscosity of the
material is markedly lowered in the course of the transformation of the polymer into a low molecular
substance, and furthermore, the microparticles of the particles are caused. Therefore, it was introduced
in the sequence processing to convert the organic chlorine compounds in the bottom ash into inorganic
chlorine, thereby lowering the chlorine content. Hydrothermal experiment was conducted with 50g of
bottom ash at the reactor, the reactor was sealed in a cylindrical pressed holder and heated by electric
resistant container, raised the temperature of the heating jacket up to the critical state, and then use an
agitator to distribute them evenly. The experimental conditions were 2.0 Mpa of pressure, the mixing
speed of agitator was 200 rpm, the ratio of water to sample was 5:1 and the temperature ranged from 0,
180, 200, and 220 to find the optimal temperature conditions.

Abstract. Different biomass (walnut shell, coconut shell or cottonwood sawdust) were co-pyrolyzed with carbon-enriched oily sludge to produce activated carbons (ACs) for phenol adsorption. The activated carbons using K2CO3 as activated agent were prepared by one- step or two- step activation and their characteristics were investigated. The textural morphology was examined by scanning electron microscopy and the surface functional groups were determined by FTIR spectroscopic method. Co-carbonization of the biomass materials and the oily sludge could develop micro-mesopore, widen pore distribution of activated carbon significantly and achieve phenol super-adsorbent. The maximum BET surface area was 1342 m2/g for the ACs prepared from the mixture of walnut shell and oily sludge by one-step activation. The maximum phenol adsorption capacity could be up to 200.581 mg/g achieved by the activated carbon prepared from the coconut shell and the oily sludge by one-step activation. Higher micropore surface area of ACs prepared from the mixture, higher phenol adsorption capacity they had. The capacity of phenol adsorption of ACs prepared from the mixture of walnut and oily sludge was between which prepared from the individual starting material, although it had the widest pore distribution, which is suggested that it was also influenced by the number of CO. .Keywords: Activated carbon; Oily sludge; Biomass; Adsorption; Co-carbonization

Abstract:
In this work, the polyvinyl chloride(PVC) and xylan were selected to research the interaction during co-
pyrolysis. The co-pyrolysis characteristics and product yields under different mass ratio were studied via
TGA analysis and a fixed-bed reactor. The pyrolysis process of PVC can be divided into three stages
from 240oC to 530oC, while the xylan decomposition occurred in the temperature range of 180~350oC.
Interaction was observed to reduce the tar yield and promote the char yield compared with the linear
calculation according to the fixed-bed experimental results. In addition, detailed product species of rapid
pyrolysis were analyzed by py-GC-MS, and the char was detected by Roman spectrometer. Interaction
can be proved in the process of co-pyrolysis.

Abstract:
For efficient hydrothermal treatment of kitchen waste, this study aims to figure out the correlations between complex chemical constitution of typical kitchen waste and the physicochemical structure of their derived hydrochar, which could be utilized to adjust hydrochar properties for specific applications (e.g., adsorbent, fuel) by regulating respective proportions of each component in kitchen waste. Cellulose, hemicellulose and lignin were used as the control variables of composition of orange peel waste, while protein and fat were used as the control variables of composition of kitchen-wasted-lettuce in this work. After hydrothermal process of orange peel waste, lignin added feedstock produced more hydrochar, which contained rougher surface with nearly doubled BET areas and more benzene rings. Hemicellulose-aided hydrochar possessed higher density of carbonaceous microspheres and richer hydroxyl. This char was simultaneously covered by more esters or lactones with more aromatic oxygen-containing groups inside. Similar to hemicellulose, cellulose improved the formation of diverse oxygenous groups but reduced the size of microspheres on hydrochar. As for hydrothermal process of lettuce waste, the Maillard reaction between proteins and reducing sugars occurred, which promoted the aromatization of the organic intermediates and increased the content of nitrogen-containing heterocyclic functional groups on the surface of hydrochar. Fat did not participate in the carbonization reaction, but its main hydrolyzates, fatty acids, were adsorbed to the surface of hydrochar.

Abstract:
Biomass pyrolysis as a route for energy production is attracting worldwide attention, and tar is one
of the main products during such process. The upgrading and effective utilization of tar is a key issue
for the sufficient application of biomass pyrolysis technology. For tar upgrading, homogenization and
pollutants control are among the major challenges facing most researchers. Molten alkali metal salt,
containing large specific heat and thermal conductivity coefficient, can store and provide solar heat to
tar reforming process. More attractively, molten alkali carbonates are able to implement catalytic
cracking of carbonaceous compounds and in situ capture of pollutants, such as H2S and COS.
Accordingly, molten carbonates are feasible reaction medium for homogeneous and catalytic upgrading
of tar. The aim of the present study is to explore the thermochemical conversion features of tar in molten
salt and find a competitive means for its high-value utilization. The experiments were carried out in a
self-design reactor filled with molten carbonates. Toluene, one of the major tar components, was selected
as tar model compound representing light aromatics. Three main contributors were generally
investigated, i.e., temperature, atmosphere and low molecular compounds in tar.
The results showed that, compared to that of conventional thermal cracking, the gas productivity
(H2 and CH4) of toluene was significantly reduced by 91.60% (650 °C), 84.45% (750 °C) and 62.18% (850
°C) in molten salt. A high molar ratio of CO2 and 10 wt.% CaCO3 in molten salt reforming would also
dramatically suppress H2 yield. Interestingly, liquid productivity and a tendency towards polycyclic
aromatic hydrocarbons (PAHs) formation were enhanced in molten salt thermochemical conversion
58
process. In detail, chain substance took about 65.27 area% after reforming with CO2 at 650 °C in the salts.
However, with temperature increasing from 750 to 850 °C, the area percentage of 2 rings groups grew
from 69.64 to 87.87 area% in the carbonates, in which dibenzyl took 59.86 area% at 750 °C; dibenzyl,
dimethylbiphenyl and stilbene summed up to 86.98 area% at 850 °C (Fig. 1). Alkali metal cations inclined
to enhance the break of C-H bonds and ring-opening reaction, accompanied by H radicals' generation.
But the CO3²- and CO2 tended to deplete the H radicals, thus molten salt reforming was promising medium
for directional conversion of tar into some specific value-added PAHs.

On the contrary, alcohols and carboxylic acids contents in tar could notably raise the total gas yield
(H2, CH4 and CO). In the meantime, the liquid product alerted from PAHs to straight chain substance in
the presence of CO2 (Fig. 2). Particularly, 48.56 area% of oleanitrile was obtained in the molten salt with
a quarter volume ratio of methanol. Alcohols and carboxylic acids could provide with free radicals (e.g.,
OH, H and CH3 radicals) to induce thermal decomposition of aromatics. Despite that the OH radical could
react with molten alkali carbonate salts to generate less active carbonate radical and hydroxyl (CO3²- +
OH· CO3·- + OH-), the inhibition of CO3²- and CO2 on aromatic ring reduction could be neutralized to
some extent. Therefore, introducing OH and H-containing substance in tar molten salt reforming is
recommended for synthesis of producer gas and chain substance, such as oleanitrile and octadecenamide.

Abstract. The understanding of liquid breakup mechanism is the point of many industrial applications. When propellant fuel burns, it melt, liquefied, and liquid droplets break up into smaller size droplet; it then results in less inertia which has a higher chance of following the exhaust gas stream instead of impinging to machine components. In this study, the propellant melt breakup due to the interaction with a high-speed gas combusted gas flow is conducted by investigating the fluid property. The result of a melt breakup is obtained using computational fluid dynamic simulation technique with the use of large eddy simulations (LES). The results are then compared with the experiment. The result presents the reduction of droplet size by changing the liquid surface tension. The mechanism of droplet breakup is discussed which is found to be due to the lower Laplace pressure or droplet bounding force balance lead by the lower surface tension of the liquid.

Abstract:
Thailand is one of the top ten largest coconut producing and exporting countries in the world. Coconut meat and juice are the main products to serve the food and pharmaceutical industries. Nowadays, plenty of coconut wastes are generated including the wastes from fruit processing such as carp, shell and the wastes from plantation i.e. leaf, bunch and leaf stalk that are not efficiently utilized. In the viewpoint of energy production, coconut wastes have been reported as the good quality fuels with high heating values (17 – 18 MJ/kg dry) and low ash content when comparing with other agricultural residues such as rice husk and rice straw. Due to the relatively low bulk density, pelletisation of coconut wastes was applied in this study. Pellets from five coconut wastes including coconut shell (CSh), coconut carp (CC), coconut exocarp (CExo), coconut leaf (CL) and coconut leaf stalk (CLS) were prepared by using a flat-die pellet machine with capacity 50 kg/hr. Basic fuel properties and combustion characteristics of the pellets were analyzed and compared with the commercial wood pellet. To investigate the combustion characteristics, combustion tests were conducted using both a thermogravimetric analyzer (TGA) and a lab-scale combustor. The property analyses show that the coconut waste pellets had the good pellet qualities in terms of high bulk density, low N and S content, high heating value, high mechanical durability (DU) and low percentage of the fine particle, which meet the EU wood pellet standard (EN plus B). However, the higher Cl and ash content than those of wood pellet are the main technical concern before utilizing. The combustion tests reveal that coconut shell pellet (CSh) was the best fuel among five coconut pellets providing the highest combustion temperature and lowest gas emission. In addition, the CSh had similar combustion behavior to the commercial wood pellet. Keywords: coconut waste, coconut waste pellet, combustion, pellet quality, biomass pellet

Abstract: For the superheater of a biomass power plant in China, explosion accidents frequently occur. Five
biomass fuels used in the power plant were analyzed. The results showed that the chlorine content of
wood chips and fungi is high, reaching 0.57% and 0.35% respectively. When the chlorine content in fuel
is greater than 0.3%, the high temperature corrosion tendency associated with chlorine is serious. At the
same time, X - ray diffraction and energy spectrum analysis were carried out on the interception section
of superheater fracture. The study shows that the main components of the deposit are KCl and NaCl,
which aggravate the deposition and further promote the high temperature corrosion. Finally, a high
temperature corrosion experiment was designed to study the corrosion characteristics of the superheated
material. The results show that temperature, HCl, alkali metal and water vapor all have great influence
on the corrosion rate. Proper control of the above factors can reduce the degree of corrosion.

Abstract:
The UN 2030 Agenda for Sustainable Development encourages both public and private sectors to
contribute in achieving the 17 Sustainable Development Goals (SDGs), which include 169 targets
covering all social, economic, and environmental dimensions. Thai government incorporated SDGs as
the key agenda to be addressed in its 12th National Economic and Social Development Plan and the 20-
yr National Strategy. The government has to rely on private sector’s contribution to achieve the national
targets. In the past few years, the Stock Exchange of Thailand (SET) and some Thai listed companies
have been very active in promoting sustainability practices; however, their understanding and
contribution to the SDGs remain unclear. This study investigated their perspectives, policy, and planned
actions towards SDGs using structural equation modelling technique of partial least square. The findings
can contribute to understanding current directions and conditions of Thai listed to integrate government

ICIPEC-0073 High temperature corrosion in superheater tubes under different flue gas conditions
- .
Abstract. Higher efficiency waste to energy plants have been required by the Japanese government since The Great East Earthquake of 2011. Increasing the temperature and pressure in the superheated tubes can be an exceptional solution to improve energy efficiency. In this research, high temperature corrosion tests were carried out in three waste to energy plants. The results of tests show that the melting point of ashes and the average thickness loss of the tubes varied according to different flue gas temperatures. Under flue gas temperature of 520 C to 540 C, the ash melting point increased to 700 C, and as a result, the corrosion by molten salt was mitigated. These test results were applied to a new boiler design with a steam condition of 450 C × 6MPa, which is currently under construction.

Abstract: Aiming to expand trade to achieve the target of US$15 billion bilateral trade by 2020, agreement between Cambodia and Thailand has been made to build a favorable business, cross-border development, and investment climate between the Asian neighbors. Freight transportation is an important economic activity driving cross-border economic growth especially since bilateral trade between both countries has grown notably. As of 2018, the majority of Thai-Cambodia freight movements is still in road transport mode. This mode of transportation is a cause of many negative impacts such as traffic accidents, congestion, and air pollution. This study aims to estimate potential international freight transport between Thailand and Cambodia that can be shifted from road to rail transport, which may help improve the efficiency of current freight transportation and its environmental impacts. Official data is collected from Aranyaphathet Customs House (ACH) database for the study. Activity-based approach is used to calculate CO2 emission from each transport mode, which is based on volumes, distances, and emission factors for truck and train. The estimated potential freight volumes that can be shifted to rail are approximately 1.3 million tonnes per year based on consideration of the physical characteristics of goods from 2011-2017. This amount is equivalent to 58% of total import from Thailand to Cambodia, which could result in a 37% reduction in CO2 emission. Likewise, an approximate 1 million tonnes of freight volumes could be shifted for the goods exported from Cambodia to Thailand, which is equivalent to 96% and could result in 61% of CO2 emission reduction per year of the same period.

Abstract. In this study, decomposition of HFC-134a were investigated using three reagents, γ-Al2O3, MgO and CaO. γ-Al2O3 showed the best performance but a decrease in conversion occurred due to deactivation of the catalyst. To prevent the fluorination to the catalyst, adsorbent was added into the system to create a catalyst-adsorbent reactor. In a consequence of using adsorbent, the hydrogen fluoride produced from the decomposition reaction will react with the adsorbent, instead with the catalyst, thus the catalytic activity can be maintained for a longer period. γ-Al2O3 and MgO were selected to make a catalyst and adsorbent reactor. One stage catalyst-adsorbent and mixed configurations were found to enhance the catalytic activity and high HFC-134a conversion can be maintained to longer time. In order to explain the effect of adsorbent, the comparison of fresh and spent used in the single-bed catalyst and catalyst-adsorbent configuration was investigated. Characterization test, such as XRD, TGA, EDS and BET were conducted to analyze the change of the condition of fresh and spent γ-Al2O3 and MgO. Considering the satisfactory result of reactor configuration when high-priced catalyst can be combined with low-cost adsorbent, this proposed configuration is an economic method for HFC-134a abatement that can also reduce the operational cost.

Abstract:
Waste-to-Energy technology becomes crucial concept since large amount of municipal solid waste (MSW) causes aggravatingly environmental impact. In Thailand, approximately 75 kton of MSW was generated daily in 2017 and Bangkok possessed 17.8% of that huge amount while 26.2% of them were unsanitary disposal. Hence, thermal conversion technology by gasification plays important key role for sustainable solution. In this work, gasification experiment was conducted in small dropped tube fixed bed reactor by feeding surrogate MSW which including of food & kitchen waste, plastic (polyethylene & polypropylene), paper, rubber & leather, textile
and biomass. The experimental conditions were varied at temperature 700, 800 and 900°C. Steam was supplied as gasifying agent with flow rate of 0.1, 0.2 and 0.3 ml/min. The main purpose was to produce hydrogen by water gas-shift reaction, nevertheless, other related producer gas e.g. carbon monoxide, methane, carbon dioxide and light hydrocarbon gas were
included in report. The result show reaction temperature 800°C with steam flow rate 0.2 ml/min offer the optimized hydrogen yield as 34.84 gH2
/kgMSW whereas it trended to decrease in above
temperature. In addition, the overall performance of experimental condition was evaluated by energy output and energy conversion efficiency which were calculated from volumetric of combustible gas. The minimum energy output and energy conversion efficiency were 7,638
kJ/kgsample
and 31.11%, respectively, obtained from temperature 700°C with steam flow rate 0.2
ml/min while the maximum was offered by reaction temperature 900°C with same steam flow rate as 17,755 kJ/kg
sample and 72.32%, respectively.

Abstract: Volatile organic compounds existing within the indoor environment of small enterprises (hair salons, barbershops, nail shops, printing shops, laundry) may result to adverse health effects to both workers and customers upon continuous exposure. Similarly, identified VOCs in these small businesses are also included in the list of ozone precursors that cause harm in the environment. However, these gases were detected at low concentrations, making their control very challenging. This study focused on the degradation of low concentration VOCs and the control parameters that result to the highest decomposition efficiency. Non-thermal plasma technique was used in this study to decompose dilute concentration of VOCs in air. The non-thermal plasma reactor utilized was a surface dielectric-barrier discharge type and the VOC concentration was fixed at 10 ppm. A gas circulation system was added to continuously circulate the target gas after initial passage through the reactors. The effect of gas circulation was investigated by re-circulating the gas at 70%-90% of the initial flow rate (1.5-1.7 L/min). Effect of other parameters such as voltage and frequency (3.8~4.3 kV, 60~120 Hz) were also investigated in this experiment. The system performance was evaluated in terms of conversion ratio of the VOC to CO and CO2 and the energy efficiency of the decomposition process. Concentrations of ozone and the presence of other by-products at the outlet were also detected.

Abstract:
Due to the more stringent emission regulation such as NOx emission standards, SCR(Selective Catalytic Reduction) catalyst demand is increasing, and the amount of waste catalyst generation is expected to increase accordingly. Used catalysts are classified as specified wastes in Korea. And they are usually recycled by physical regeneration and recovery of valuable metals is limited due to cost incurred during treatment. There exist some limitations such as number of regeneration, expensive cost for valuable metal recovery and discarding of TiO2 which accounts for 85 to 90% of the catalyst.
A study on chemical washing and purifying process for toxic substance in the poisoned SCR catalyst and optimal solvent for higher valuable metal/TiO2 contents were carried out for more economical SCR catalysts utilization with extended lifetime.
Through chemical treatments using 5 solvents for removal of poisonous materials, acetic acid showed the highest catalyst regeneration efficiency of 1.19 wt%(originally 1.65 wt%) for V2O5 content, and removal efficiency of 57.6 % for total poisonous materials. Measurements with different concentration of solvent and cleaning time were also carried out to find out the effect on V2O5 content and the poisonous materials removal efficiency.
Through this study, 0.1N acetic acid was found to be the most suitable cleaning solvent and concentration for the chemically poisoned catalysts used in SCR processes.

Abstract:
In this study, optical characteristics such as asbestos shape, refractive index, sign of elongation and extinction characteristics were observed by using a polarizing microscope in the heat treatment process of chrysotile, amosite and crocidolite. In addition, The diffraction peaks obtained by the X-ray diffraction(XRD) of chrysotile were compared with the diffraction peaks of the asbestos before heat treatment to analyze the crystal structure change. Among the optical properties, the refractive index of chrysotile at each temperature tended to increase continuously in the horizontal and vertical directions with time. When heat treatment was carried out at 1100 for 10 minutes, the refractive index in the horizontal direction was 1.650 and the refractive index in the vertical direction was 1.658, and sign of elongation changed from (+) to (-). On the other hand, when chrysotile was heat treated at 300 for an extended time, the horizontal and vertical refractive indexes tend to decrease with time, and sign of elongation did not change (+). The refractive index of crocidolite was 1.688 in the horizontal direction and 1.698 in the vertical direction, unlike chrysotile and amosite, the sign of elongation was (-). In addition, XRD analysis of chrysotile showed that the diffraction peaks could not be identified at higher temperature above 800 , and the change of crystal structure could be confirmed. This result can be used for qualitative analysis when asbestos used as building material, is denatured due to fire.

Abstract:
A lot of effort has been done to reduce the nitrogen oxidation (NOx) generated from the high-temperature combustion reaction of the fossil fuel at the stationary sources, such as industrial facilities, power generation plants, boilers. Technologies have been applied after the combustion by using the catalytic reactors and reduction agents in most cases. Initial investment expenses and operation costs have shown some limitations in actual applications. Researches also have been done to investigate to reduce thermal NOx at its NOx generation step. In this study, the characteristics for the NOx formation together with the issue of combustion efficiency in the combustion process were investigated by utilizing an internal recirculation-type low-NOx burner. A pilot-scale test combustion facility was tested to find the characteristics of NOx generation following the operation requirements with variables adjustment. In addition, a commercial computer fluid dynamic software, ANSYS FLUENT (Fluent V.13.0, ANSYS, USA) was used to apply a numerical interpretation to verify the model. Various burner types were applied to establish detailed fluid structure in three dimensional analysis that is difficult to measure empirically the heat fluid flow and combustion characteristics for the internal flame formation. As a ANSYS FLUENT program results of the numerical interpretation for NOx level generated from combustion chamber, it was shown that the highest NOx level was in the order of normal burner > LNB-5way>2-stage>LNB-8way. When the internal fluid flow pattern with the LNB-5way burner combustion was analyzed, it showed that the flow of internal re-circulation from the high speed flame was observed with vertical the gas inflowing.

Abstract:
Simple absorption systems have been utilized in Korea to control complicated odorous substances from odor emission sources like leather manufacturing processes and pure water is generally supplied as absorbing solution. There should exist some limitations in controlling odorous substances in effective manner. In this study, operating parameters were investigated to analyze their effects on the odor control
efficiencies of the wet scrubbers at wastewater treatment facilities in the leather manufacturing process with the purpose of deriving feasible guidelines for maintaining the performance of the wet scrubber system in odor emission sources. Odor dilution ratio, level of specific odor substance and operating conditions of the scrubber (COD,
pH) were monitored to analyze the scrubber performance. The main odor substance from the leather manufacturing process was considered based on H2S. The odor control efficiencies were analyzed largely dependent on COD concentration and pH of scrubbing solution. As a result, it could be considered that lower COD level and higher pH should be maintained for improved odor control efficiencies.

Abstract:
A significant amount of engineered nanomaterials (ENMs) commercially employed for various industrial activities eventually ends up in sanitary landfills. The objective of this study was to investigate the behavior of the microbial community in nano-ZnO spiked simulated landfill reactors. Therefore, in order to evaluate the impact of one of the most widely-used ENMs, namely zinc oxide (ZnO), simulated bioreactor and conventional landfills were run using real solid waste samples obtained from a sanitary landfill for about a year with addition of nano-ZnO. Leachate samples were taken at different phases from the reactors and they were analyzed using 16S rRNA gene amplicon sequencing. The bacterial communities were distinctly characterized by Cloacamonaceae (Phylum: WWE1), Rhodocyclaceae (Phylum: Proteobacteria), Porphyromonadaceae (Phylum: Bacteroidetes) and Synergistaceae (Phylum: Synergistetes). The bacterial community in the bioreactors shifted at the end of the operation and dominated by Rhodocyclaceae. There was not a major change in the bacterial community in the conventional reactors. The methanogenic archaeal diversity highly differed between the bioreactors and conventional reactors. The dominance of Methanomicrobiaceae was observed in the bioreactors during the peak methane-production period. However, their prominence shifted to WSA2 in the nano-ZnO-added bioreactor and to Methanocorpusculaceae in the control bioreactor towards to the end. Methanocorpusculaceae was the most abundant family in both conventional control and nano ZnO containing reactors.

Abstract:
A higher attention has recently been directed towards utilization of renewable energy sources in order to substitute fossil fuel sources and to decrease emissions of greenhouse gases (GHGs) released into the atmosphere to mitigate climate change. Among the renewable energy sources, biomass plays a very significant role for both developed and developing countries to reduce GHGs emissions. Particularly, production of biogas from biomass has significantly developed worldwide during the last couple of decades, since biogas can easily be used for production of power and heat. In addition, after up-grading, bio-methane can be used as a substitute of natural gas or as a fuel in vehicles. Energy crops, manure, agricultural residues and organic wastes can be used for biogas production in agricultural or centralized biogas plants. Agricultural resources and particularly, animal manure is an important substrate for agricultural biogas plants for renewable energy production. Furthermore, there exits many studies covering use of various pretreatment methods applied for biomass for enhanced biogas yields. Batch anaerobic digestion tests were conducted according to the guidelines outlined in German VDI 4630 method (VDI 4630). Cow manure was obtained from a farm. The seed sludge (inoculum) was obtained from a sewage wastewater treatment plant in Istanbul. The samples were kept at 4°C prior to use. Two sets of experiments were performed at mesophilic temperature (37±1°C). The biogas experiments lasted for 60 days. Two parallel reactors were run and the average results are reported. Biogas production was daily measured using Milligascounters (Ritter, Bochum, Germany). The composition of biogas, namely methane (CH4) and carbon dioxide (CO2), was determined using a GC-TCD. The measurements of pH and solids were conducted according to the guidelines outlined in Standard Methods (APHA, 1988). According to preliminary findings, methane yield of 0.20159 L CH4/g VS was obtained. Methane content of the biogas produced mostly ranged between 56-64%.

Vellore institute of technology, Vellore, India
Abstract. This paper presents an effective experimental approach that can be applied to stationary single cylinder LPG fuelled lean burn SI engine. This approach has been applied to operate the engine under different equivalence ratio at wide open throttle condition. Experiments were conducted at a constant speed of 1500 rpm and at compression ratio of 10.5:1. In this study the effects of adding small amount of ethanol (5%, 10% and 20%) along with LPG were investigated. Ethanol on volume basis was injected along with carburetted LPG. A maximum brake thermal efficiency of 28.5% with 10% ethanol addition for LPG were observed at an equivalence ratio of 0.7. The ethanol addition with LPG extended the lean limit as compared to pure LPG. Also, it was observed that 10% Ethanol addition resulted in reduced HC and CO emissions due to oxygen present in the ethanol. The combustion parameter shows increased heat release rate and reduced cyclic variations with 10% ethanol addition. The optimal ethanol blend with LPG was found to be 10% for better performance and reduced emissions.

Abstract:
Ozone (O3) is a commonly known air pollutant that causes adverse health effects. This study developed a multi-level prediction model for conjunctivitis in outpatients due to exposure to O3 by using three years of ambient O3 data, meteorological data, and hospital data in Seoul, South Korea. We confirmed that the rate of conjunctivitis in outpatients (conjunctivitis outpatient rate) was highly correlated with O3, temperature, and relative humidity. A multi-level regression model for the conjunctivitis outpatient rate was well-developed, on the basis of sex and age, by adding statistical factors. This model will contribute to the prediction of conjunctivitis outpatient rate for each sex and age, using O3 and meteorological data. This study was funded by the Korea Ministry of Environment (MOE), as the Environmental Health Action Program (2016001360005).

Abstract:
Mercury has been a focus of extensive research by many toxicologists and environmental experts due to its high toxicity and a tendency to bio-accumulate, which are very threatening to both human and ecosystem. With the increasing usage of coal in china, which has been recently showing rapid economic growth, it is known that over 50% of mercury emissions in the world generated in Asia. Moreover, it is reported that mercury of about 10 to 30 tons has been generated every year from artificial pollution sources in Korea. The major sources of mercury examined were coal-fired power plants, municipal solid waste incinerators, iron manufacturing plants and cement factories. The distributions of gaseous and particulate mercury in flue gas were 93.3~98.94% and 1.36~6.67%. Therefore, in order to remove the mercury effectively, it is important to control the gaseous mercury. Accordingly, this study investigated mercury control technology and implemented adsorption experiments using several activated carbon and zeolite impregnated with various chemicals such as sulfur, chlorine, copper, nickel. The characteristics of impregnated ACs were analyzed using XPS and XRF. The efficiency of Hg0 adsorption increased with temperature in the case of Cu/Cl-impregnated adsorbents. The result show that both types of impregnated ACs and Zeolite may be enough to remove highly elemental mercury. Also it can be explained that the reaction between chloride and Hg0 has exothermic behavior, catalytic oxidation occurred by transition metal including Cu. In conclusion, the high chemical activity of metal/halogen on porous materials leads to good elemental mercury adsorption

Abstract Biomass is fuel that has been developed from organic materials; a renewable and sustainable source of energy used to create electricity or other energy of steam. In South Korea, a number of boilers and power generation facilities using biomass continue to increase. As a result, Korea currently has 67 biomass facilities, of which 47 (thus 70 percent) use FBC type (Fluidized Bed Combustion). Among them CFBC (Circulating Fluidized Bed Combustion) facilities are also increasing in areas such as large power plants. Furthermore, the installation of BFBC(Bubbling fluidized bed combustion) is also increasing in smaller facilities. Waste wood turned to Bio-SRF has witnessed a dramatic increase in use over the past four years(From 2014 to 2017) in Korea (293% ), and the consumption of waste wood that included importing goods has also showing increase up to 469 percent. We have our own BFBC technology and also reference at Harim food plant . It is possible to use
various biomass fuels such as wood pallets, wood chips, PKS(palm kernel shells), bana grass, dried sludge, livestock manure, etc.

Abstract. Zinc-air batteries exhibit high potential for various energy applications because of their cost-effective and high specific energy. An electrolyte is an essential element of zinc-air batteries. The development of the electrolyte, particularly polyelectrolyte, is a crucial research issue. Research into polyelectrolytes is receiving much attention, nowadays. In this work, polyelectrolytes were prepared from poly(vinyl alcohol) (PVA), Carbopol940 and potassium hydroxide (KOH) using a solution casting method. Mixtures of PVA, Carbopol940 and KOH, each having a different weight ratio, were poured onto a filter paper and left to dry naturally, at room temperature, for 24 hrs. Then, the samples were immersed in 8M KOH aqueous solution. The ionic conductivity of the prepared polyelectrolytes was in the range of 0.136 – 0.293 S.cm-1 at room temperature. To examine the stability and behavior of the polyelectrolytes, cyclic voltammetry using a two-electrode configuration of Zn|polyelectrolyte|Zn cell was carried out. Thus, it was found that the polyelectrolytes of PVA and Carbopol940 (1:0.75) exhibited the highest electrochemical stability. The discharge capacity of the zinc-air battery, using the polyelectrolyte of PVA and Carbopol940 (1:0.75), was measured at a discharge current of 10 mA. The cyclability of the batteries was investigated at discharge and charge current of 10 and 25 mA, respectively. Also, the polyelectrolyte of PVA and Carbopol940 (1:0.75) provided the highest cyclability and cyclic discharge energy.

Abstract:
Thailand has an enormous biomass potential that can be a promising solution to the growing demand for electricity in the country. In order to develop a biomass facility, meticulous planning is essential to ensure the cheap and clean energy. This study considers environmental and socio-economic constraints to determine the suitable locations for a biomass power plant in southernmost provinces of Thailand. Weights of the criteria were evaluated by using experts opinion as an input for the Analytic Hierarchy Process (AHP). Floodplain emerged as the most influencing criteria within the environmental parameters and the residential buffer was a leading criterion among socioeconomic parameters. The AHP weights were then used in GIS environment to manipulate and present the spatial data. They were then aggregated using overlaying feature in GIS to determine the suitable sites for a biomass facility and it was divided into four suitability classes namely, “Highly”, “Moderately”, “Low” and “Unsuitable” areas. Our work offers a scientific methodology that can be reproduced to conduct studies of similar nature in other regions.
Keywords: Biomass facility, GIS, Multicriteria assessment, Thailand.

Abstract:
The aims of this paper are to investigate the energy balance on an integrated energy production system using water hyacinth as biomass fuel with no electricity supply to the system. The conceptual framework of the present study is to use water hyacinth as primary energy source input into gasifier through the gasification process. The producer gas produced will be used as energy input to drive the other parts of the system that be connected with the gasifier. The integrated energy production system comprise of three main parts such as (1) collection system of fresh water hyacinth from canal or river (2) briquetting system of water hyacinth and (3) gasification system using water hyacinth briquettes as biomass fuel. The collection system of fresh water hyacinth comprises of two parts such as pontoon and conveyer belt. The briquetting system comprises of four parts such as squeeze machine, chopping machine, drying chamber and briquetting machine. The gasification system comprises of two parts such as gasifier and gas treatment system. Based on the concept of no electricity supply to the system, thus every parts of the production system will be driven with the producer gas. The investigation was conducted based on the calculation of energy balance in the system. The calculation results based on the average value of biomass gasification rate showed that the gasifier with the capacity of 100 kg/hr can produce the producer gas at the rate of 300 m3/hr. And the total amount of the producer gas required to operate the machines installed within the site are 165.75 m3/hr in which equivalent with the amount of water hyacinth briquettes around 55 kg/hr. Thus from the energy balance analysis found that the producer gas produced from the gasifier with the capacity of 100 kg/hr can supply the energy to drive all machines installed at the site. Moreover there are the extra amount of water hyacinth briquettes produced from the system around 45 kilogram per hour.
Keywords: water hyacinth, producer gas and energy balance.

Abstract:
For the high efficiency and low cost long bag filter test, two types of 15 m bag filter in the dust collector to which the integrated filter cleaning system was applied. The bag filter uses a general filter and an air permeability control filter to evaluate the performance of the filter regeneration and the complex regeneration dust collector according to the change in conditions. In the experiment, three 15 m Bag filters were installed and the filtration speed and dust supply rate were fixed with a dust collector. Also, in the regeneration of the filter, the compressed air injection method ensured that compressed air was injected into each filter for 0.1 second when the pressure loss of the bag filter dust collector reached 100 mmH 2 O or 120 mmH 2 O. Experimental conditions were taken into consideration for filter Cleaning method and change in weak air pressure, and the filtration rate was fixed at 1.5 m/min. The processing gas flow rate corresponding to the filtration rate of 1.5 m/min was 33 m 3 /min, and the dust concentration at this time was flowed into 20 g/m 3 . Under the experimental conditions, the filter cleaning method uses the on-line pulsing method and the integrated method, and two conditions were used for the drainage air pressure of 3 kgf/cm 2 and 5 kgf/cm 2 . Filter cleaning method and attenuated air pressure bag filter pressure change of the dust collector and PM10, PM2.5, PM1 discharge concentration were compared and evaluated. Concentration of discharged dust showed a significantly low exhaust gas concentration when using Integrated Cleaning Method compared with on-line pulsing.
