Petroleum coke, commonly known as Petcoke, is a carbon-rich solid material that is derived from oil refining. It is produced during the delayed coking process, where heavy residual oils are broken down into lighter products, leaving behind solid carbon.
Petcoke is used as a fuel, carbon source, or additive in various industrial applications.
Fuel Grade Petcoke
High sulfur content
Used as industrial fuel in cement, power, brick kilns, etc.
Calcined Petcoke (CPC)
Low sulfur and volatile content
Used in aluminum, steel, and graphite industries
Needle Coke (Special Grade)
Highly crystalline
Used in electrodes for steel and electric arc furnaces
