Petroleum coke, or petcoke as it is commonly known, is a by-product of petroleum refining. Petcoke refers to all types of carbonaceous solids obtained in petroleum processing which includes green (raw), calcined and needle petroleum coke. Petcoke is used in many applications, including electrodes and anodes. It is also used as a fuel in the cement, metal and brick industries.
As a fuel, petcoke offers high calorific value properties at a competitive price, making it a very attractive energy substitute for thermal coal.
