Calcine Petroleum Coke

Calcine 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 metal content to be used as anode material. Green coke with this low metal content is called anode-grade coke. When green coke has excessive metal content, it is not calcined and is used as fuel-grade coke in furnaces.

Petroleum Coke manufactured by delayed coking of residues obtained from crude oil distillation units of Oil Refineries is called Green or Raw Petroleum Coke. The said Green or Raw Petroleum Coke calcined at a temperature 12000 centigrade to 13000 centigrade is known as CPC (Calcined Petroleum Coke). Calcined Petroleum Coke (CPC) is extensively used for melting purpose of Alumina in Aluminium industry, as a carbon raiser while making Special High Carbon Steel in Foundries, as a conductive backfill in ground Electrode station and in manufacture of various Carbon and Graphite Products.

Calcined petroleum coke (CPC) has a sponge-like structure which plays an important role in the making of anodes. The pores allow binding material to penetrate through the coke particles and form a solid carbon block, through which aluminum smelters conduct electricity into their smelting pots. Over time, the anodes are consumed, roughly at the rate of 40 tons of calcined petroleum coke for each 100 tons of aluminum producead. Currently, there is no known commercially viable substitute for calcined petroleum coke in the fabrication and utilization of aluminum smelter anodes.
