Conversion of coal from its solid form to a gaseous fuel (or, gaseous chemical) is widely practiced today. During earlier years (1920–1940), coal gasification was being employed to produce manufactured gas in hundreds of plants worldwide, and such plants were called manufactured gas plants (MGPs). This technology became obsolete

Mar 10, 2017· Coking coal must also have low sulphur and phosphorous contents. Almost all metallurgical coal is used in coke ovens. The coking process consists of heating coking coal to around 1000-1100ºC in the absence of oxygen to drive off the volatile compounds (pyrolysis). This process results in a hard porous material – coke.
