Carburizing agent for petroleum coke


Petroleum coke carburizer manufacturer Guanji editor today to talk to you about the calcination of petroleum coke related knowledge. 

Petroleum coke is composed of hydrocarbons, containing 90-97% carbon and 1.5-8% hydrogen, as well as nitrogen, chlorine, sulfur and heavy metal compounds. 

Petroleum coke is a black or dark gray hard solid petroleum product, with metal luster, porous, is composed of tiny graphite crystallization into granular, columnar or acicular carbon. 

Petroleum coke is a by-product when the feedstock oil of delayed coking unit is cracked to produce light oil at high temperature. 

The amount of low fever is about 1.5-2 times that of coal, the ash content is less than 0.5%, the volatile content is about 11%, and the quality is close to that of anthracite. 

The output of petroleum coke is about 25-30% of the raw oil. 

In this way, the hydrogen content of petroleum coke reproducts can be reduced, the graphitization degree of petroleum coke can be improved, the high temperature strength and heat resistance of graphite electrode can be improved, and the electrical conductivity of graphite electrode can be improved. 

Calcined petroleum coke is calcined in order to meet the requirements of graphite electrode for steelmaking or anode paste (melting electrode) for making aluminum and magnesium. 

The calcination temperature is generally about 1300 ℃. The purpose is to remove the volatile components of petroleum coke as far as possible. 

The calcination temperature is generally about 1300 ℃. The purpose is to remove the volatile components of petroleum coke as far as possible. 

Calcined petroleum coke is calcined in order to meet the requirements of graphite electrode for steelmaking or anode paste (melting electrode) for making aluminum and magnesium. 

It can also be directly used as coke for blast furnace in metallurgical industry or carbon brick for blast furnace wall, and it can also be used as dense coke for forging process. 

Calcined coke is mainly used to produce graphite electrode, carbon paste products, diamond sand, food grade phosphorus industry, metallurgical industry and calcium carbide, among which graphite electrode is widely used. 

The coke can be directly used as calcium carbide as calcium carbide main material and silicon carbide and boron carbide as grinding materials without calcination. 

To learn more about petroleum carburizers, you can consult the graphitized petroleum coke manufacturer in detail.
