Calcined Petroleum Coke (CPC) is the product from calcining petroleum coke. This coke is the product of the coker unit in a crude oil refinery. The calcined petroleum coke is used to make anodes for the aluminum, steel and titanium smelting industry. The green coke must have sufficiently low metals content in order to be used as anode material.
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. The primary aluminum industry is the major consumer of calcined petroleum coke, representing approximately 80% of the demand for this carbon material. The balance of calcined coke demand originates from the steel and chemical industries, mostly as recarburizer. CPC is also used in foundries for casting process.
