COAL GASIFICATION - monographs.iarc.fr

During coal gasification, coal is reacted with oxygen, steam and carbon dioxide to form a gas containing hydrogen and carbon monoxide. During this process, which is essentially incom-plete combustion, the heat evolved is consumed and the sulfur and nitrogen in the coal are converted to hydrogen sulfide (rather than sulfur dioxide) and ammonia (rather than nitrogen oxides), respectively. These ...
