Information

The past and present of graphite petroleum coke is a kind of thermal processing coking device in petrochemical industry, mainly processing petroleum coke and some light oil products with poor residual quality, which are difficult to further process. Loss of coke in natural stone production will also be divided into ordinary petroleum coke and high-quality petroleum coke. This is also the origin of graphitized petroleum coke. The main difference between them is whether they are used as raw materials for graphite electrodes and other advanced graphite products.

Generally speaking, ordinary petroleum coke does not have high quality requirements, and the light oil produced is also low-quality oil with high residual carbon value and high metal technology content. It must undergo a secondary processing method. Develop qualified oil products. Natural graphite appears in nature. People often use graphite in the foundry industry. Because of the many advantages of artificial graphite, such as the porosity, carbon content, and graphitization degree of artificial graphite, they can all be controlled to meet the requirements. Petroleum coke is mainly used to produce graphite.

Our low-sulfur and low-nitrogen Graphitized Petroleum Coke is made of calcined petroleum coke which is raw material, going through fully continuous graphitization process under the high temperature of minimum 2600℃ . Through crushing, screening and classification, we supply different particle size between 0-50mm at the customers' request. As the preferred material for high-end customers in the casting industry, "XINTAN" carbon raiser has excellent characteristics of high carbon content, good absorption rate and stable quality
