May 29, 2015· Petroleum coke, or petcoke, is a granular coallike industrial byproduct that is separated during the refinement of heavy crude oil. Recently, the processing of material from Canadian oil sands in refineries has led to the appearance of large petcoke piles .
Petroleum coke (often abbreviated pet coke or petcoke) is a carbonaceous solid delivered from oil refinery coker units or other cracking processes.

Under these mild "catalytic" conditions, less expensive reactor components can be utilized, pipeline grade methane is produced, and very lowcost carbon sources (such as lignites, subbituminous coals, petroleum coke and biomass) can be used as feedstock.
Petroleum coke is produced by coking liquid petroleum residues and pitches in metal coke vats or special furnaces. Petroleum coke is also formed during cracking and pyrolysis of products of petroleum distillation. Pitch coke and petroleum coke are the main raw material for producing electrodes.

The petroleum coke produced by a coking unit is generally referred to as green petroleum coke. Green petroleum coke contains relatively minor concentrations of volatiles, which are removed in a calcining unit. The volatiles would be catastrophic if introduced into molten metal.

ASTM's petroleum standards are instrumental in the evaluation and assessment of the physical, mechanical, rheological, thermal, and chemical properties of crude oils, lubricating grease, automobile and aviation gasoline, hydrocarbons, and other naturally occurring energy resources used for various industrial applications.
The concentration of impurities in raw materials (particularly petroleum coke) is increasing and testing the ability of cast houses to meet customer chemical specifications. Much of the metal content (Ni, V) of the coke and impurities in alumina (Fe, Si, Ga, Zn) reports to the aluminium in the reduction cells.
