Coal gasification - Wikipedia

Typically coal contains anywhere from 0.2 to 5 percent sulfur by dry weight, which converts to H 2 S and COS in the gasifiers due to the high temperatures and low oxygen levels. These "acid gases" are removed from the syngas produced by the gasifiers by acid gas removal equipment prior to the syngas being burned in the gas turbine to produce electricity, or prior to its use in fuels synthesis.

Coal gasification - Wikipedia

Jump to navigation Jump to search. Coal gasification is the process of producing syngas —a mixture consisting primarily of carbon monoxide (CO), hydrogen (H 2 ), carbon dioxide (CO 2 ), natural gas ( CH 4 ), and water vapour (H 2 O)—from coal and water, air and/or oxygen. Historically, coal was gasified to produce coal gas, also known as "town gas".
