Calcined Petroleum Coke commonly known as CPC is produced from Raw Petroleum Coke (RPC) also called the Green Petroleum Coke. The result of the calcining process is converting green coke to hard, dense and almost pure carbon with low hydrogen content, good electrical conductivity and a defined structure. These properties alongwith low metals and ash contents make calcined petroleum coke the best material currently available for making carbon anodes for smelting of alumina to aluminium in the electrolytic smelting process. CPC holds significant importance in the manufacturing of aluminium, and is also utilised in the production of steel and various other carbon-based products. It is widely used in aluminium industry, titanium dioxide industry, electrode manufacturing industry, foundry industry, glass industry metallurgical and chemical industry, and steel industry etc. The process entails heating raw petroleum coke to eliminate volatile impurities, resulting in enhanced properties that make it highly suitable for various manufacturing processes.
