Coke Making Process

Coke is produced by igniting bituminous coal under reduced oxygen conditions in oven batteries specially designed for this process. The coking process generates the following main volatiles as byproducts: coke oven gas, tar, ammonium sulfate, benzol, toluol and naphtha. A coke battery is made up of multiple ovens.

12.2 Coke Production

Metallurgical coke is produced by the destructive distillation of coal in coke ovens. Prepared coal is heated in an oxygen-free atmosphere (–coked–) until most volatile components in the coal are removed. The material remaining is a carbon mass called coke. Metallurgical coke is used in iron and steel industry processes (primarily in blast furnaces) to reduce iron ore to iron. Over 90 ...

Coal Carbonization for Coke Production – IspatGuru

2018-12-08  The coal to coke transformation takes place as the coal is heated. When the state of fusing is reached, the layer of heated coal softens and fuses. From around 375 deg C to 475 deg C, the coal decomposes to form plastic layer. Destructive distillation reactions proceed rapidly in the plastic layer with the evolution of volatile products.
