Coke (fuel) Wikipedia

Coke (fuel) Raw coke. Coke is a grey, hard, and porous coalbased 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 ...

10 Coal Carbonisation ScienceDirect

This chapter discusses coal carbonization. Coal carbonization involves the destructive distillation of coal, and during this process, as much as 50% of the weight of the coal feedstock is driven off as gaseous and volatile components. These are regarded as byproducts of the coking process, and include combustible gases (for example, methane ...
