The difference between graphitized petroleum coke and calcined petroleum coke

The difference between graphitized petroleum coke and calcined petroleum coke 1: production process

Graphitized petroleum coke: Graphitized petroleum coke means that petroleum coke has been graphitized. So what is the graphitization process? Graphitization is the change in the internal structure of petroleum coke when it undergoes a high temperature of about 3000 degrees. The molecules change from randomly arranged carbon crystals to regularly arranged carbon crystals. This process is called graphitization. Compared with calcined petroleum coke, graphitized petroleum coke mainly has lower sulfur content and higher carbon content, which can be as high as 99%.

Calcined petroleum coke: Calcined petroleum coke is the product of high-temperature calcination of petroleum coke. The temperature is mainly controlled at about 1300 degrees. Most of the water and volatile matter in the petroleum coke can be removed through calcination. The fixed carbon content of calcined petroleum coke is generally more than 98.5%.

The difference between graphitized petroleum coke and calcined petroleum coke 2: Application

Graphitized petroleum coke and calcined petroleum coke are mainly used in steel plant smelting and casting manufacturing industries. However, due to different production processes, graphitized petroleum coke has the advantages of low sulfur, low nitrogen, and high carbon. Graphitized petroleum coke is more suitable for gray cast iron. Casting and ductile iron with strict sulfur requirements.

Difference 3 between graphitized petroleum coke and calcined petroleum coke: Appearance

Calcined petroleum coke: From the appearance, calcined petroleum coke is black lumpy particles with irregular shapes and different sizes, with strong metallic luster and transparent carbon particle pores;

Graphitized petroleum coke: In addition to the appearance of calcined petroleum coke, graphitized petroleum coke is darker and brighter in color and has a stronger metallic luster than calcined petroleum coke, and can be printed directly on paper smoothly. Make traces.

The above three points are the differences between graphitized petroleum coke and calcined petroleum coke.

The difference between petroleum coke carburizer and graphitized carburizer

Carburizers are mainly divided into petroleum coke carburizers and graphitized carburizers. Graphitized carburizers are made from petroleum coke carburizers as raw materials and through high-temperature graphitization. The production processes of the two are also different.
The most intuitive way to distinguish is: graphitized carburizer can be written on paper, while petroleum coke carburizer cannot.
