    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. Metallurgical coke has an 85 to 90% fixed carbon content ...
