Pet coke. Also known as: coke, refinery coke, petroleum coke. Pet coke is the solid carbon byproduct of cracking units such as the the FCC and coker unit.. In an FCC, coke forms on the catalyst and is burned off as fuel for the FCC process, resulting in no net production of coke as a product.. In a delayed coker, resid is thermally cracked to produce lighter, more desirable products.

Raw coke. Coke is a grey, hard, and porous coalbased fuel with a high carbon content and few impurities, made by heating coal or oil in the absence of air—a destructive distillation process. It is an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges when air pollution is a concern.. The unqualified term "coke" usually refers to the ...

The cooked coal, called coke, is removed from the oven after 18 to 24 hours of reaction time. The coke is cooled and screened into pieces ranging from one inch to four inches. The coke is a porous, hard black rock of concentrated carbon (contains 90 to 93 percent carbon), which has some ash and sulfur but compared to raw coal is very strong.

Coking coal, or metallurgical coal, has been produced in the United States for nearly 200 years. Coking coal is primarily used in the production of coke for use in the steel industry, and for other uses (for example, foundries, blacksmithing, heating buildings, and brewing). Currently, coking coal is produced in Alabama, Arkansas, Pennsylvania, Virginia, and West Virginia.
