Coal gasification - Wikipedia

Coal gasification is the process of producing syngas —a mixture consisting primarily of carbon monoxide (CO), hydrogen (H 2 ), carbon dioxide (CO 2 ), methane (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".
