# Calcined Petroleum

Calcined Petroleum Coke. Calcined Petroleum Coke is a critical ingredient in the production of aluminum. It is created by placing high quality raw “green” petroleum coke into rotary kilns, where it is heated to temperatures between 1200 to 1350 degrees C (2192 to 2460 F).

Green petroleum coke is generated by delayed distillation of coal during the conversion of crude oil into liquid fuels such as gasoline and jet fuels. Calcined petroleum coke (CPC) is produced from green petroleum coke through a process known as ‘calcining’, which removes moisture and volatile matter from green petroleum coke at a very high temperature. CPC is crucial to the electrolytic production of aluminum.
