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), 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"Coal gas is combustible and was used for municipal lighting, and heating
