Gasification technology of the western industrialized countries
When pulverized coal is injected into a high-temperature and high-pressure gasifier synthesis gas is formed from the volatile and the char components. Synthesis gas or Syngas is a mixture of carbon monoxide (CO) and water (H2O).
From the synthesis gas, which is formed in the coal gasification process, it is possible to synthesize various chemical products such as hydrocarbon fuels (gasoline/light oil) and methanol and ammonia.

Coal Flash Partial Hydopyrolysis Technology is a technology which causes rapid reaction to pulverized coal under high pressure (2-3Mpa) and in a moderate hydrogen atmosphere to highly efficiently obtain, from one reactor, synthetic gas easy to be evolved such as into Integrated Gasification Combined-Cycle (IGCC) power generation, indirect liquefaction (GTL), and chemicals while co-producing light oil as chemicals and fuel. The realization of a coal-based cross-industrial composite project (led by electric power/ chemistry/ steel) with this technology as its core will hopefully bring a dramatic improvement to total energy utilization efficiency.●Basic partial hydropyrolysis test (1996-1999, 1kg/d) using a small-scale test unit●PDU test (2000-2003, 1t/d, *NSC in-house research) using a reforming/partial oxidation-integrated PDU test unit●Pilot plant test (2003-2008, 20t/d) Test are conducted, using a PP having its thermally self-supportable reactor together with other ancillary process units, to have forecasts for a demonstration unit (up to 1,000t/d) as the next step.
