Coke is a gray, hard, porous, high-carbon, low-impurity coal-based fuel produced by heating coal or oil in the absence of air. This is a destructive distillation process. It is an important industrial product, primarily used in the smelting of iron ore, but also as a fuel for furnaces and forgings where air pollution is a problem.
