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.
