The figure of gasification reactions and transformations illustrated the concept of coal gasification, and noted resulting composition of syngas. This can vary significantly depending on the feedstock and the gasification process involved; however typically syngas is 30 to 60% carbon monoxide (CO), 25 to 30% hydrogen (H 2), 0 to 5% methane (CH 4), 5 to 15% carbon dioxide (CO 2), plus a lesser ...

Gasification is a thermochemical process for the conversion of a solid organic material, typically coal or biomass, into syngas. From a chemical point of view, gasification occurs due to the partial oxidation of a solid material at temperatures of 700900 °C by means of a gasifyingoxidant agent, such as air, oxygen, steam or carbon dioxide.
