Petroleum Coke is a solid, carbon-rich material, derived from crude oil refining. More specifically, coke is a bottom of the barrel by-product, result of the end of the cracking process. It is a grayish-black solid, that is usually distinct in two varieties: fluid coke, and flexicoking coke (although other classifiions are used, such as needle, honeyco, sponge, shot and others).

Petroleum coke - Wikipedia
Petroleum coke, abbreviated coke or petcoke, is a final carbon-rich solid material that derives from oil refining, and is one type of the group of fuels referred to as cokes.Petcoke is the coke that, in particular, derives from a final cracking process—a thermo-based chemical engineering process that splits long chain hydrocarbons of petroleum into shorter chains—that takes place in units
Calcined Petroleum Coke(CPC) | Saba Zob Sepahan …
Finally, through the production process, crude coke is converted to the calcined coke which contains a high level of stabilized carbon, and low levels of ash and sulfur. Petroleum coke, compared with metallurgical coke enjoys a higher thermal value and the absorption factor of petroleum coke is much higher that of the metallurgical one (about 10%).
