Coke is the most important product of coking. Its main components are fixed carbon, followed by ash. It contains very little volatile matter and sulfur. It is silver-gray, has a metallic luster, is hard and porous. In most countries, more than 90% of coke is used for blast furnace ironmaking, followed by foundry and non-ferrous metal smelting industries, and a small amount is used to produce calcium carbide, carbon disulfide, elemental phosphorus, etc. In steel joint ventures, coke powder is also used as a sintering fuel. Coke can also be used as a raw material for preparing water gas to produce raw gas for synthesis.
