Coal gasification is the process of producing syngas: a mixture consisting primarily of carbon monoxide (CO), hydrogen (H2), carbon dioxide (CO2), methane (CH4), and water vapour (H2O)—from coal and water, air and/or oxygen. Rather than burning coal directly, gasification converts all of the carbon of the coal into electricity, hydrogen, and ...

The importance of the gasification process comes from the ability to produce energy for electricity generation, energy carrier (in the case of H 2) and chemicals (methanol, DME, and so on) from the direct conversion of syngas (Lopez et al., 2018).Steam is the most preferable gasifying agent for the production of higher amount of H 2 [Eq. ()] in the syngas with a calorific value of around 12 ...

Syngas production by gasification processes ScienceDirect

Gasification is a thermochemical process by which fuel is broken down into a product gas and ash. It occurs at high temperatures using a gasifying agent under substoichiometric conditions. This product gas, or gasification gas, generated by gasification processes differs chemically from syngas.

Underground coal gasification (UCG) is an industrial process which converts coal into product gas. UCG is an insitu gasification process, carried out in nonmined coal seams using injection of oxidants and steam. The product gas is brought to the surface through production wells drilled from the surface. The predominant product gases are methane, hydrogen, carbon monoxide and carbon dioxide.
