Petroleum coke is the "waste" at the end of the petroleum refining process. Therefore, the technology of replacing heavy oil with petroleum coke powder is a typical circular economy ["Petroleum coke powder replacing heavy oil technology"], and it is also a good way for new energy applications.
Classification And Properties Of Petroleum Coke
Needle coke: It has obvious needle-like structure and fiber texture. It is mainly used as high-power graphite electrode in steelmaking. Needle coke has strict quality index requirements in terms of sulfur content, ash content, volatile content and true density.
Sponge coke: high chemical reactivity, low impurity content, mainly used in aluminum smelting industry and carbon industry. Shot coke (spherical coke): spherical in shape, 0.6-30mm in diameter, generally produced from high-sulfur, high-asphaltene residues, and can only be used as industrial fuels such as power generation and cement.
Powder coke: It is produced by fluidized coking process, with fine particles (0.1-0.4mm in diameter), high volatile content, and high thermal expansion coefficient, so it cannot be directly used in electrode preparation and carbon industry.
Petroleum Coke Powder Processing Technology
After the petroleum coke is first crushed by the crusher, it is dried by the dryer (some do not need to be dried), and then strongly ground by the MTW European version mill to produce petroleum coke powder that meets customer requirements. The conveying system is continuously, uniformly and stably sprayed into the kiln for combustion in a quantitative manner.
