Coke from coal is grey, hard, and porous and has a heating value of MJ/kg. Some cokemaking processes produce byproducts, including coal tar, ammonia, light oils, and coal gas. Petroleum coke (petcoke) is the solid residue obtained in oil refining, which resembles coke but contains too many impurities to be useful in metallurgical appliions.
