The petroleum coke from the delayed coking unit is called raw coke, and the process of heat treatment of high temperature (1250~1380 °C) under the condition of insulating air is called calcination. The petroleum coke after calcination is called calcined petroleum coke, also called Calcined coke and calcined petcoke, they have different names but are the same product. The purpose of calcination is to discharge moisture and volatiles in the raw materials, so that the petroleum coke raw materials are sufficiently shrunk to improve their physical and chemical properties.
Calcined petroleum coke is a high purity carbon material produced by heating green petroleum coke to drive off moisture, volatile matter, and impurities and to increase its electrical conductivity, which is used to improve the carbon content in steel-making and ductile iron foundry. It is widely used to produce graphite electrode, graphite blocks, brakes pads and other carbon products. it can also be used as carbon additive in some steel and aluminum plants, another, it is used in refractory, insulation, filler,etc. We can supply different grades of Calcined Petroleum coke.
