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 termed coker units.
