Petcoke

Petroleum coke (petcoke) is one of many valued consumer products produced during the oil refining process. Crude oil is processed into gasoline, diesel fuel, jet fuel, lubricating oils and waxes, leaving some residual crude that usually undergoes additional processing.

The crude residue may be further refined by a process known as coking to produce transportation fuels as well as petcoke, which has a variety of uses as an alternative, cost-effective fuel. Coking is not a new technology. The first modern coker in the U.S. was installed in the 1930s. Currently, petcoke is produced at more than 140 refineries around the world.

Uses of Petroleum Coke:
Petroleum coke is typically used as a source of energy, or as a source of carbon for industrial applications. Fuel grade petcoke represents nearly 80 percent of worldwide production and is a source of fuel for cement kilns and electric power plants. Calcined petcoke has the highest carbon purity and is used to manufacture energy, as well as in the aluminum, graphite electrode, steel, titanium dioxide and other carbon consuming industries.
