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. ... A similar product called petroleum coke, or pet coke, is obtained from crude oil in oil refineries.Inexhaustible natural resources are the resources which can used for long time as they are the most abundant resources in nature.
