    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

    It was found that the optimum CC preparation temperature was 250 °C (CC250) for high strength coke preparation. 4. Whereas increasing the blending ratio of CC250 to caking-coal decreased the coke strength, the extent of the decreasing strength was smaller than that of slightly-caking coal or pyrolyzed char blended with caking coal. 5.
