Calcined Petroleum Coke is a carbonaceous solid derived from oil refinery coker units or other cracking processes.
Calcined petroleum coke is a black or dark gray hard solid petroleum product with metallic luster and porosity. It is a carbonaceous material composed of fine graphite crystals in the form of particles, columns or needles. The petroleum coke component is a hydrocarbon containing 90-97% carbon, 1.5-8% hydrogen, and nitrogen, chlorine, sulfur and heavy metal compounds. Calcined Petroleum Coke is a carbonaceous solid derived from oil refinery coker units or other cracking processes.The production of petroleum coke is about 25-30% of the feedstock oil. The low calorific value is about 1.5-2 times of coal, the ash content is not more than 0.5%, the volatile matter is about 11%, and the quality is close to anthracite.
For casting, cast iron, cast steel, castings will have a requirement for carbon, Calcined Petroleum Coke is to increase the carbon content of iron liquid, for example, in the melting of the commonly used charge for the pig iron, scrap, back to the material, pig iron Carbon content is high, but the purchase price relative to the scrap is to be higher than a section, so increase the amount of scrap, reduce the amount of pig iron, plus carbon agent, can play a certain role in reducing the cost of casting.
