Coal gasification coal processing Britannica

Coal gasification, any process of converting coal into gas for use in illuminating and heating. The first illuminating gas was manufactured from coal in England in the late 18th century by the process of carbonization or destructive distillation, heating coal in the absence of air, leaving a residue of coke as a by-product. Such coal gas was widely used for street lighting and home

Coal gasification commercialization Wikipedia

Coal gasification is a process whereby a hydrocarbon feedstock (coal) is converted into gaseous components by applying heat under pressure in the presence of steam. Rather than burning, most of the carbon-containing feedstock is broken apart by chemical reactions that produce "syngas." Syngas is primarily hydrogen and carbon monoxide, but the exact composition can vary.
