Coal gasification
Coal gasification is a process that converts coal from a solid to a gaseous state. The gas that is created is known as syngas or synthesis gas.
Pronunciation
Coal gasification: /koʊl ˌgæsɪfɪˈkeɪʃən/
Etymology
The term "coal gasification" comes from the word "coal", which is derived from the Old English "col", and "gasification", which is derived from the word "gasify". "Gasify" is a combination of "gas" and "-ify", a suffix used to form verbs expressing transformation into the kind of thing indicated by the base noun.
Process
Coal gasification involves the reaction of coal with oxygen, steam, and carbon dioxide to form a gas that contains hydrogen, carbon monoxide, and carbon dioxide. This process is carried out at high temperatures and pressures. The resulting gas can be used for various purposes, including the production of electricity, synthetic fuels, and chemicals.
