Metallurgical coke is widely used in various industries in Japan. In a coke furnace, coal is heated indirectly (for 14 to 18 hours at 1,200 to 1,300°C) and then carbonized (dried by distillation) for about 24 hours. Subsequently, it is fractionated into coke and other materials, such as gases, tar oil, benzene, toluene, and naphthalene.
