MTBE:
Relevance in Today’s World
April 23, 2013
Doha, Qatar
Middle East MTBE Workshop
CLEAN FUEL, CLEAN AIR
Working closely with fuel policymakers,
regulators and stakeholders in the fuel industry,
ACFA promotes and advances the use of
cleaner automotive fuels based on principles of
sound science, cost efficiency and
sustainability of the environment.
Who is ACFA?
MTBE has NEVER been classified as toxic or
carcinogenic by any regulatory body anywhere
in the world.
MTBE Facts

MTBE Facts
1. The European Union conducted a 3-year MTBE risk
assessment based on 20+ years of European MTBE
usage and research.
Conclusion:
•MTBE is a safe and beneficial gasoline component
•When used and handled properly, MTBE is not expected to have any
harmful impact on human health and the environment.
•Potential to cause odour and taste problems in water, need to consider
a risk reduction strategy for groundwater and drinking water
• Proposals mainly dealing with the construction and operation of
petrol underground storage and distribution facilities at service
stations

MTBE Facts
2. WHO reviewed the impact of MTBE use on public
drinking water.
Conclusions:
• MTBE is non-genotoxic
• Insufficient data to reach any conclusions about its potential
to cause human cancer
• Did not see any reason to restrict the use of MTBE in gasoline
5
All these reputable bodies have found no
sufficiently compelling reason to classify MTBE as a
possible cancer-causing agent for humans:
6
• The Clean Air Act Amendments of 1990 (in the
US) established the Reformulated Gasoline
(RFG) program, which included an oxygenate
mandate.
– The requirement for oxygenates could be met with
either ethanol or MTBE
– MTBE captured approx. 85% of the oxygenate
market.
– MTBE was a product approved and mandated by the
federal government.
• California found MTBE in groundwater and
drinking water supplies in 2000/2001, and
moved to ban the use of MTBE in 2003.
Let us go back to where it all started…
7
• The Energy Policy Act of 2005 removed the oxygenate
mandate for RFG and instead established the
Renewable Fuel Standard, requiring ethanol content in
gasoline.
• Once the oxygenate mandate expired, refiners stopped
blending MTBE in the U.S. for liability concerns.
• In considering the Energy Policy Act, the Congress
REJECTED an amendment calling for a federal ban on
the use of MTBE.
• While a number of states maintain MTBE bans on their
books, there is NO federal ban on the use of MTBE.
• In fact, there is still MTBE production in the U.S. for
export markets in Mexico, Venezuela and Europe.
The facts of MTBE in the USA
8
• The Initial Problem: Public Perception versus
Reality
– Lack of focus on true problem: leaking gasoline tanks
– Overestimation of risk to water resources
– Overreaction to odor/taste thresholds
– Convergence of political influence of powerful lobbies
• The Result: Adverse public reaction particularly
in California & Northeast
– Incorrectly framed issue as a choice between clean
air and clean water
– MTBE became a convenient “scapegoat”
The U.S. Experience:
Sound Science vs. Political Science
9
• According to statistics compiled by the U.S.A.
Oxygenate Fuels Association, the introduction
of MTBE in gasoline has resulted in the
reduction of common air pollutants.
– 20-25% less carbon monoxide
– 20-30% less benzene
– 5% less nitrogen oxides
– 15% less evaporative emissions
– 30% less particulate matter
– 10-15% less unburned hydrocarbons
US Experience: MTBE Reduce Air Pollutants

THE RELEVANCE OF MTBE
• 1990s: Middle East and Asia/Pacific.
• The main driving force in Middle East was
the need of MTBE for lost octane from
lead phase out and as high sulphur levels
are gradually reduced in gasoline.
• In Asia/Pacific the main driving force was
the real necessity of clean air through
cleaner fuels legislation.
• MTBE begun to be commonly imported in
Taiwan, Thailand, and largely produced
and consumed in Saudi Arabia, South
Korea, Singapore and Malaysia.

Italics – under discussion; a – gasoline; b – diesel; c – Entire country; d – Delhi, Mumbai, Kolkata, Chennai, Hyderabad, Bangalore, Lucknow, Kanpur, Agra, Surat, Ahmedabad, Pune and Sholapur;
Other cities in India are in Euro 2; e – Beijing [Euro 1 (Jan 1999); Euro 2 (Aug 2002); Euro 3 (2005); Euro 4 (1 Mar 2008); Euro 5 (2012)], Shanghai [Euro 1 (2000); Euro 2 (Mar 2003); Euro 3 (2007);
Euro 4 (2010)] and Guangzhou [Euro 1 (Jan 2000); Euro 2 (Jul 2004); Euro 3 (Sep-Oct 2006); Euro 4 (2010)]; f – Equivalent to Euro 4 emissions standards; g – for gasoline vehicles only

• Octane replacement due to fuel
quality improvements (lead phase-
out, reduction in sulphur, benzene,
aromatics, olefins).
• Expanding vehicle fleet and
growing gasoline demand.
• Vehicle technology advances need
cleaner fuels to meet the stricter
emissions standards and to operate
as designed.
• Increase in minimum octane grade.
• Growing demand for higher grade
gasoline.
• Market is octane-short (especially
clean octane.)

• Vapor pressure improver
• Gasoline pool volume extender
• Excellent blending octane value
• Refinery blending flexibility
• Economic/cost effectiveness advantages
– Avoids heavy capital investment
– Lower operating costs
• Fully compatible with transport/handling systems
• Improves vehicle performance (such as drivability & cold
starting)
• Readily available world-wide and locally produced

• The octane number improvement with MTBE in
general depends on the base gasoline.
• Clear octane numbers for MTBE are relatively
high and therefore MTBE is used widely to
improve the octane rating for gasoline.

MTBE GROWTH OPPORTUNITIES
• Asia and Middle East to boost MTBE demand
• South and Central America and Africa
– Scope for further penetration of MTBE, paving the
way for potential increase in demand in the future.
• Growing gasoline markets in developing markets
– Gasoline blending was the major consumer of MTBE
at global level, followed by solvents and chemical
reagent applications.
• Improved gasoline quality requirements
• Phase out of metallic octane boosters
• Low biofuels penetration rate in developing nations
Global MTBE Demand Drivers
24
• Growing emphasis on renewable fuels /
sustainability
– Risk of reduction of gasoline consumption in general
– MTBE may be edged out in gasoline pool as not
produced from renewable sources
• Biofuels mandates in EU and USA.
• Risks of declining gasoline consumption in
developed nations
– FFV and alternative energy
– Fuel economy improvement
– Dieselization
– Market maturity and aging demography
• Groundwater concerns

• MTBE has NEVER been classified as toxic or
carcinogenic by any regulatory body anywhere in the
world. Safe and beneficial gasoline component.
• Responsible care is critical to the long term sustainability
of the MTBE industry
– When used and handled properly, MTBE is not expected
to have any harmful impact on human health and the
environment.
• Tighter vehicle emission standards and fuel quality
legislation will support MTBE’s long term viability and
sustainability in the fuels landscape in the Middle East
and Asia.
