CPC
Calcined Petroleum Coke (CPC) is manufactured from Raw Petroleum Coke (RPC) by the process known as high temperature pyrolysis. The process is carried out in a rotary or vertical kiln at temperatures exceeding 1300 deg C. Calcination of CPC is essentially a high temperature treatment in which the carbon to hydrogen ratio of RPC is increased from 20 to 1000 and above. Calcination is achieved by complete demoisturisation and dehydrogenation of RPC under controlled conditions. During the process molecular rearrangement takes place making the CPC electrically conductive, an essential property required for Aluminium smelting.
