Coal

Coal application in our life
① burning. Coal is an important energy resource of human, no coal can be used as industrial and domestic fuel. ② coking. Coal in the retort furnace, isolated air heating, coal organic matter with increasing temperature is gradually broken down, volatile substances escaping gaseous or vapor state, coke oven gas and coal tar residual non-volatile solid The matter is the coke. Coke oven gas is a fuel, is also an important chemical raw materials. Coal tar can be used for the production of chemical fertilizers, pesticides, synthetic fibers, synthetic rubber, paints, dyes, pharmaceuticals, explosives. The coke is mainly used for blast furnace iron making and casting, and can also be used to produce nitrogen fertilizer, calcium carbide. Calcium carbide is a synthetic plastics, synthetic fibers, synthetic rubber and other chemical products. The ③ gasification. Gasification is converted to gas as industrial or civil synthetic fuel and chemical raw materials.
