Graphite petroleum coke in the previous life was a coking unit in the petrochemical industry that had a large thermal processing category. The main purpose was to treat residual oils that were of such poor quality that it was difficult to further process them, coking them to produce petroleum coke and Some light oil products. The coke produced will naturally be divided into ordinary petroleum coke and high-quality petroleum coke. This is also the origin of the graphitized petroleum coke. The difference is mainly whether it can be used as an electrode and other advanced graphite products.

Generally speaking, the quality of ordinary petroleum coke is not high, and the light oil products produced are also high quality oil products with high residual carbon value and high metal content, which must undergo secondary processing to obtain qualified oil products. In addition, there will be natural graphite in nature, but artificial graphite is often used in casting, because artificial graphite has many advantages, such as the porosity, carbon content, and degree of graphitization of artificial graphite can be controlled, which can better meet It is required that petroleum coke is mainly used for producing graphite at the same time.
