Coking - Wikipedia

Coking is the heating of coal in the absence of oxygen to a temperature above 600 °C, to drive off the volatile components of the raw coal, leaving a hard, strong, porous material of high carbon content, called coke. Coke consists almost entirely of hydrocarbons. The porosity gives it a high surface area, which makes it burn faster (as does a sheet of paper versus a wooden log). When a kilogram of coke is burned it releases more heat than a kilogram of the original coal.

Coke (fuel) - Wikipedia

Coke is a grey, hard, and porous 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. 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 cr…

What is Coking Coal - Aspire Mining Limited

The Chinese coking coal market is likely to be the largest consumer for Ovoot coking coal due to its size and proximity. Premium coking coals such as Fat (Ovoot coal) and Primary coals, are in particular high demand within China primarily due to the low ratio of these coals in China’s own coal reserves but also due to the growing requirement for higher quality coking coals in the coke industry.
