Coke is a fuel with few impurities and a high carbon content, usually made from coal. It is the solid carbonaceous material derived from destructive distillation of lowash, lowsulfur bituminous coal. Cokes made from coal are grey, hard, and porous. While coke can be formed naturally, the commonly used form is manmade.

Most of the chemicals derived from coal come from byproducts produced during the coking process. Coal is used to make coke to make steel. Coke gas (also called foul gas) contains coke tars, ammonia, and light oils. Tars are recovered and used to make tar derivatives. Ammonia is recovered as an aqueous solution or as an ammonium sulfate salt.

General Metallurgical coke is produced by the destructive distillation of coal in coke ovens. Prepared coal is heated in an oxygenfree atmosphere (coked) until most volatile components in the coal are removed. The material remaining is a carbon mass called coke.

The coke ovens were used to convert the coal mined in the local area into industrial coke, a relatively cleanburning fuel used in the smelting of iron ore. In a process known as "coking," coal was shoveled into an insolated beehiveshaped and ignited. What is a coke stove? The industrial production of coke from coal is called coking.

The unqualified term "coke" usually refers to the product derived from lowash and lowsulphur 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. [1] History China

Carbonization, more narrowly defined, refers to conversion of a starting material into carbon, or a carbonrich solid. It is entirely possible, and indeed often done, to pyrolyze a hydrocarbon feedstock for the purpose of carbonization, but carbonization is not simply pyrolysis by another name.

1. When coal is heated to a certain temperature while cutting out air supply, it turns into a residue of solid carbonaceous form known as coke. 2. The nature of the residue depends on the temperature at which the coal is heated. Generally it is hightemperature carbonization which helps convert coal to coke.
