CALCINED PETROLEUM COKE (CPC)
Calcined Petroleum Coke (CPC) is obtained by heating green petroleum coke at a temperature as high as 1400 ℃. With high electrically conductive and low specific electrical resistance, CPC is widely used in the aluminum anode, graphite electrode and other carbon consuming industries.

GRAPHITE PETROLEUM COKE (GPC)
High quality green petroleum coke (CPC) is taken into Acheson furnace for graphitization process with temperature around 2500-3600 ℃. The product has higher degree of graihitization with nitrogen content s lower than 300ppm. This product with lower sulphur and ash content is ideal recarburizer for steelmaking foundry industires.
