WebCoal tar is produced through thermal destruction ( pyrolysis) of coal. Its composition varies with the process and type of coal used – lignite, bituminous or anthracite. [38] Coal tar is a mixture of approximately 10,000 chemicals, of which only about 50% have been identified. The unqualified term "coke" usually refers to the product derived from low-ash and low-sulphur bituminous coal by a process called coking. A similar product called petroleum coke, or pet coke, is obtained from crude oil in oil refineries. Coke may also be formed naturally by geologic processes.
