• Søderberg anodes are made in situ from a paste of calcined petroleum coke, coal tar pitch and anode butts, which is baked by the heat arising from the molten bath. The current is fed into

Calcined Petroleum Coke (CPC) | Basetrade Global

Anode grade coke is treated by thermal decomposition at temperatures below its melting point to remove moisture and volatile coustible matter. This process, known as calcination, thus improves the coke’s critical physical properties such as its electrical conductivity, real density and oxidation characteristics.

Petroleum Coke Industries Co. (KSCC): Product & Process …

Calcined Petroleum Coke (CPC) is obtained by Calcining Raw Petroleum Coke (RPC) at temperature around 1200-1350 C. RPC is the end product of the Oil refining process and derived from the fractional distillation of Petroleum Crude in delayed Cokers. CPC is mainly used in the Aluminum Smelter.

Petroleum Coke

Needle coke is crystalline in nature and is used for dry cells and electrodes. Calcined petroleum coke is made when petroleum coke is calcined, or roasted, just below the melting point. This coke is commonly used in the smelting industry for the creation of
