Coal gasificationWikipedia

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 vapor (H2O)–from coal and water, air and/or oxygen. Historically, coal was gasified using early technology to produce coal gas . In thes every small to medium-sized town and city had a gas plant to
