Petroleum coke has its unique physical, chemical and mechanical properties. It is the non-volatile carbon of the heat-generating part. The indicators of volatiles and mineral impurities (sulfur, metal compounds, water, ash, etc.) determine the chemical properties of petcoke.
According to the structure and appearance of petroleum coke, petroleum coke products can be divided into needle coke, sponge coke, shot coke and powder coke. The purpose of each type of petroleum coke is different.
