Carbon Monoxide, Hydrogen
Syngas or synthesis gas, is a fuel gas mixture consisting primarily of hydrogen, carbon monoxide and very often some carbon dioxide. Syngas is combustible and often used as a fuel of internal combustion engine. The syngas is produced by gasification of a carbon containing fuel to a gaseous product that has some heating value.
