Calcined Petroleum Coke is the product of raw petroleum coke after calcined at 1300ºC temperature. In the calcination process, the structure and element composition of various carbonaceous have undergone a series of deep changes, which eliminate the moisture and volatile matter in petroleum coke, improve the density and mechanical strength of products, and improve the electrical conductivity and antioxidant properties of raw petroleum coke.
