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…
It requires the coal/coal blends in proper proportions with certain characteristics of such blends for better yield of coke. The characteristics of coals vary from a coking coal to a non-coking one. For the effective utilization of non-coking coals, these are blended with coking coals to achieve those certain characteristics required for coke making.
