Natural deposits of graphite, coal tar, and petroleum coke are important sources of elemental carbon. Coined with carbonaceous binders, such as tars, pitches, and resins, the carbon is compacted by molding or extrusion, and baked at between 816°C and 1649°C to produce what is known as industrial carbon or baked carbon.

Cokes - Carbon and Graphite

When petroleum coke is produced by the delayed coking process which is a mild slow carbonising procedure of crude oil distillation residues, it is called green or raw coke. It still contains considerable amounts (approximately 5 to 12%) of aliphatic constituents, hydrogen and heteroelements; which, at elevated temperatures, are set free as volatile matter.
