Coal Gasification - an overview | ScienceDirect Topics

Coal gasification processes are a source of synthetic natural gas, though they are under development. The gas produced from steam–oxygen coal gasification consists of H 2, CO, CH 4, CO 2 and unreacted steam. In cases in which air is used as the oxygen source, the gas is diluted with N 2.

Gasification | WCA - World Coal Association

Emissions from gasification can be easily captured because of the high pressure and, often, concentrations. Coal is the primary feedstock for gasification and will continue to be the dominant feedstock for the foreseeable future. The current growth of coal as a gasification feedstock is largely as a result of new Chinese coal-to-chemicals plants.
