What factors determine the quality of petroleum coke powder?


Graphitized petroleum coke factory

Petroleum coke powder is widely used in industry, so what factors can determine the quality of petroleum coke powder? in fact, the factors that determine its quality mainly include purity, particle size, cleanliness, and so on. 

Today, the technical staff of Lianyungang Guanji Mineral products Co., Ltd. will explain it in detail for you. 

1. Purity of petroleum coke powder. 

Refers to the content of sulfur and ash in petroleum coke powder. 

High sulfur coke will cause gas expansion of products during graphitization, resulting in cracks in carbon products. 

High ash content will hinder the crystallization of the structure and affect the performance of carbon products. 

2. Particle size of petroleum coke powder. 

The relative content of powdered coke and bulk granular coke (available coke) in reaction coke. 

Most of the powder coke is broken by mechanical action such as extrusion friction in the process of coke removal and storage and transportation, so its amount is also a kind of mechanical strength. 

The crushing of raw coke can be prevented by calcining mature coke. 

The petroleum coke powder with more particle coke and less powder coke has high application value. 

3. Crystallinity of petroleum coke powder. 

The size of a structure and mesophase sphere. 

The coke formed by the small sphere has a porous structure such as sponge, and the coke formed by the large sphere has a dense structure such as fiber or needle, and its quality is better than that of sponge coke. 

In the quality index, the true density roughly represents this kind of property, and the high true density indicates the good crystallinity. 

4. Thermal shock resistance of petroleum coke powder. 

Refers to the cracking resistance of coke products under the thermal shock of sudden rise to high temperature or rapid cooling from high temperature. 

The determination of the quality of petroleum coke powder needs to be determined on the basis of a variety of use conditions. The above four points can be used as reference points. I hope it will be helpful to you.
