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.

Physical and chemical characteristics:
high strength 
fixed carbon content
low sulfur 
low volatile matter content

They are widely used for steelmaking
ferroalloys manufacture or non-ferrous metals smelting
iron castings manufacture 
or other related metallurgical and foundry industries.

* calcined petroleum coke: Calcined petroleum coke is low sulfur, the carbon content can reach 98%. About 0.3% of sulfur and nitrogen content of around 8000.

* graphitization calcined petroleum coke:  Graphited Calcined pet-coke carbon agent is calcined coke in graphite of calcining furnace and, the carbon content can reach 98.5%, reaching 0.03% sulfur, the nitrogen content is about 300.

* graphite powder carburant: Graphite carbon additive is the milling of graphite block and high purity. Some impurities are less graphite carbon content can reach more than 99.9%. Because the graphite carburant sources on the defective graphite block, so the yield is low, demand is also smaller.
