What is Petroleum Coke? Petroleum Coke is a product in which the heavy oil is coke by distillation to separate the light and light oil, and the products are transformed into the process, from the appearance, the coke is irregular shape, the size of the black lumps (or particles), has a metallic luster, coke particles with multi-pore structure, the main elements of the composition of carbon, Possession of 80wt% (WT is the abbreviation of Weight is the meaning of weight percent content. 5WT% is equivalent to 50000PPM (PPM is millions of content)), with the rest being hydrogen, oxygen, nitrogen, sulfur and metallic elements.
Petroleum Coke has its unique physical, chemical properties and mechanical properties, itself is the heating part of non-volatile carbon, volatile and mineral impurities (sulfur, metal compounds, water, ash, etc.) these indicators determine the chemical properties of Coke.
Uses of petroleum coke: Petroleum coke, depending on its quality, is used in the production of graphite, smelting and chemical industries. Low sulfur, high quality cooked coke, such as needle-like Coke, is mainly used in the manufacture of ultra-high power graphite electrodes and some special carbon products; needle Coke is an important material for the development of new technology of electric furnace steelmaking in steelmaking industry. Medium sulfur, ordinary cooked coke, widely used in aluminum refining. High sulfur, ordinary raw coke, is used in chemical production, such as the manufacture of calcium carbide, silicon carbide, etc., but also as metal casting and other fuel.
Most of the Petroleum Coke produced in China is low-sulfur coke, mainly used for aluminium refining and graphite manufacturing. Another mainly used in the production of carbon products, such as graphite electrodes, anode arcs, to provide steelmaking, non-ferrous metals, aluminum refining, the production of carbonized silicon products, such as a variety of grinding wheels, sand skins, sandpaper, etc., the production of commodity calcium carbide for synthetic fibers, acetylene and other products; Through the JZC-1250 equipment made of coke powder to carry out combustion, the current use of coke powder fuel is mainly glass factory, coal water slurry factory and so on.
