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
