Coal gas is a gaseous mixture, mainly composed of methane, hydrogen, and carbon monoxide that are formed by the destructive distillation (it means heating in the absence of air) of bituminous coal and is also used as a fuel. At times, coal steam is added to react with the hot coke, therefore increasing the yield of gas.

Destructive Distillation: An OverviewDestructive distillation is a process used to separate various components from a substance by heating it in the absence of air or oxygen. This method is commonly employed to extract useful products from organic materials such as coal and petroleum. In the case of coal, destructive distillation produces coke, coal gas, coal tar, and ammoniacal liquor.
