Green Petroleum Coke and Calcinated Petroleum Coke | Source: JINSUN New Material Technology

Calcined Petroleum Coke (CPC) is a high-carbon material produced by thermally treating green petroleum coke (GPC) at temperatures of 1,200–1,500°C in a rotary kiln or rotary hearth furnace in the absence of air. This calcination process drives off residual volatile matter, moisture, and hydrogen, producing a dense, highly pure carbonaceous material with a fixed carbon content of 98–99 wt%. CPC is the direct downstream product of GPC and the principal carbon raw material for the aluminium smelting and steel industries.
