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.

Dr. David Gray, in Integrated Gasification Combined Cycle (IGCC) Technologies, 2017. 8.6.1 Brief history. The Shell coal gasification process (SCGP) was a byproduct of the original Shell gasification process that was developed for the partial oxidation of heavy oils and gases mostly for refinery hydrogen production. To expand the feedstock to include coal, Shell Internationale Petroleum ...

Coal gasification technology is the conversion of a carbonaceous material by reaction with oxygen and steam to produce synthesis gas (syngas) that is a feedstock to produce more valuable and higher quality liquid fuels such as diesel and kerosene. During gasification there are hundreds of simultaneous reactions taking place. However, the six principle heterogeneous and homogeneous reactions ...
