Syngas
Production

Syngas is produced by steam reforming or partial oxidation of natural gas or liquid hydrocarbons, or coal gasification.

C + H O → CO + H

CO + H O → CO + H

C + CO → 2CO

Steam reforming of methane is an endothermic reaction requiring 206 kJ/mol of methane:

In principle, but rarely in practice, biomass and related hydrocarbon feedstocks could be used to generate biogas and biochar in waste-to-energy gasification facilities. The gas generated (mostly methane and carbon dioxide) is sometimes described as syngas but its composition differs from syngas. Generation of conventional syngas (mostly H and CO) from waste biomass has been explored.
