Petroleum calcined coke

Graphitized petroleum coke

According to the structure and appearance of petroleum coke, petroleum coke products can be divided into needle coke, sponge coke, pellet coke and powder coke. 

The main results are as follows: (1) Needle coke, with obvious needle structure and fiber texture, is mainly used as high power and ultra high power graphite electrode in steelmaking. 

Because needle coke has strict quality index requirements in sulfur content, ash content, volatile content and true density, so there are special requirements for the production process and raw materials of needle coke. 

(2) sponge coke, with high chemical reactivity and low impurity content, is mainly used in aluminum industry and carbon industry. 

(3) pellet coke or spherical coke: it is spherical in shape and 0.6-30mm in diameter, which is generally produced by high sulfur and high asphalt residue and can only be used as industrial fuel such as power generation and cement. 

(4) Powder coke: produced by fluidization coking process, its particles are fine (diameter 0.1-0.4mm), high volatile content and high thermal expansion coefficient, so it can not be directly used in electrode preparation and carbon industry.
