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

Petcoke Fact Sheet - KCBX Chicago

• Coking is a thermal cracking process used to convert low value residual fuel oil to higher value gas oil, petcoke and lighter petroleum stocks. Delayed coking is the most widely used process today. Uses of Petroleum Coke • Petroleum coke is typically used as a source of energy, or as a source of carbon for industrial appliion.
