Syngas production by gasification processes ScienceDirect

Gasification is a thermochemical process by which fuel is broken down into a product gas and ash. It occurs at high temperatures using a gasifying agent under substoichiometric conditions. This product gas, or gasification gas, generated by gasification processes differs chemically from syngas.

Coal gasification Wikipedia

Coal gasification Wikipedia

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".
