The Introduction of Petroleum Coke
Petroleum coke is a by-product when the feedstock oil of the delayed coking unit is cracked at high temperature to produce light oil. The output of petroleum coke is about 25-30% of the raw oil. Its low calorific value is about 1.5-2 times that of coal, ash content is not more than 0.5%, volatile content is about 11%, and its quality is close to anthracite
The Application:
1. Low-sulfur, high-quality cooked coke such as needle coke is mainly used to manufacture ultra-high power graphite electrodes and certain special carbon products; needle coke is an important material for the development of new electric furnace steelmaking technology in the steelmaking industry.
2. Medium-sulfur, ordinary cooked coke, used in aluminum smelting in large quantities.
3.High-sulfur, ordinary green coke is used in chemical production, such as the manufacture of calcium carbide, silicon carbide, etc., and also as a fuel for metal casting, etc.
