In industrial chemistry, coal gasification is the process of producing syngas —a mixture consisting primarily of carbon monoxide (CO), hydrogen ( H2 ), carbon dioxide ( CO2 ), methane ( CH4 ), and water vapour ( H2O )—from coal and water, air and/or oxygen. Historically, coal was gasified to produce coal gas, also known as "town gas".

Conversion of coal from its solid form to a gaseous fuel (or, gaseous chemical) is widely practiced today. During earlier years (), coal gasification was being employed to produce manufactured gas in hundreds of plants worldwide, and such plants were called manufactured gas plants (MGPs). This technology became obsolete

Technologies for hydrogen (H2) production fall into four main categories: Thermal Processes: Thermal processes use the energy in various feedstocks (natural gas, coal, biomass, etc.) to release the H2 that is part of their molecular structure. The main hydrogen production technologies using fossil fuels are all thermal processes, and include reforming, gasification, and pyrolysis.

The coal gasification process results in a CO 2 stream that is very dry and about 96 percent pure, so it requires no further processing. This is in contrast to CO 2 from power plant flue gas, which is wet and diluted with nitrogen and oxygen, and requires further processing. The Synfuels Plant's gasification operation draws worldwide attention.
