Calcined petroleum coke is the product of petroleum coke calcined at high temperature. Petroleum coke calcination is an important process in the carbon production process. It is calcined at high temperature under the condition of isolating air to remove volatile matter and moisture from the raw materials. During the calcination process, the structure and element composition of various carbonaceous raw materials occur. A series of depth changes improve their physical and chemical properties, and then obtain calcined petroleum coke. Carbon particles are more transparent and have black metallic luster. More than 98.5% of the elements are carbon.
