Petroleum coke is the crude oil after the distillation of light and heavy oil separation, the heavy oil through the process of thermal cracking, the conversion of products, coke shape is irregular with different size of black lumps (or particles), with metallic luster , Coke particles with porous structure.The main composition elements are carbon, hydrogen, oxygen, nitrogen, sulfur and metal elements.

Petroleum coke can be used for making graphite, smelting and chemical industries depending on its quality. The world’s largest consumer of petroleum coke is the cement industry, which consumes is about 40% of the market share; followed by is calcined petroleum coke to produce prebaked anodes or steel-making graphite electrodes for aluminum smelting, with 22% oil Coke calcined.

Low-sulfur, high-quality cooked coke such as needle coke, which is mainly for the manufacture of ultra-high-power graphite electrodes and some special carbon products; needle coke is an important material for EAF new technology in the steelmaking industry.

Sulfur, ordinary cooked coke, which is used for aluminum refining extensively.

Sulfur, common raw coke, used for chemical production, such as the manufacture of calcium carbide, silicon carbide, but also as a metal casting and other fuels.

Besides, it’s mainly used for the preparation of carbon products, such as graphite electrodes, anode arc, provide steel, nonferrous metals, aluminum smelting; Preparation of carbonized silicon products, such as various grinding wheel, sand, sandpaper; Production of synthetic fibers, acetylene and so on; which can be also used as fuel, but it needs to ultrafine grinding at first, through Hengda high efficiency and low consumption of Raymond grinding mill into coke powder after combustion, with coke powder as the main fuel for Some glass, coal-water slurry plant.
