Distructive distillation of coal is a process of heating a complex substance coal in limited supply of air so that it breaks down into simplier substances. In this process the coal is heated to 1000 degree celcius in absence of air to obtain different useful components such as coke, coal tar and coal gas. Scholr Boy.

Burning of coal in absence of air to obtain some useful constituents is called destructive Distillation. Following constituents are obtained from this process : (i) Coke : It is a hard porous substance which is almost the purest form of carbon. It is used in manufacture of steel and in extraction of many metals.

Coke is a grey, hard, and porous coalbased fuel with a high carbon content and few impurities, made by heating coal or oil in the absence of air—a destructive distillation process. It is an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges when air pollution is a concern.
