1. Introduction of petroleum coke
Petroleum coke is the vacuum residue of petroleum. It is cracked and coked at 500-550℃ in a coking unit to produce black solid coke. It is in black or dark gray color with honeycomb structure, and the pores in the coke block are mostly oval and interconnected. There are petroleum coke of different qualities, so how to choose high quality petroleum coke?
2. Quality indicators
The quality of petroleum coke is determined by the properties of its raw materials and processing conditions. The main quality indicators include purity, crystallinity, thermal shock resistance, thermal expansion coefficient and particle size.
● Purity
Purity refers to the content of sulfur and ash in petroleum coke. High sulfur coke will cause the product to swell during graphitization, leading to cracks in carbon products. High ash content will hinder the crystallization of the structure, and affect the performance of carbon products.
● Crystallinity
Crystallinity refers to the structure of coke and the size of the mesophase spheres. Coke formed by small spheres has a porous structure like a sponge, while coke formed by large spheres has a dense structure like a fiber or needle, and its quality is better than that of sponge coke. Among the quality indicators, true density can roughly represent crystallinity, and higher true density indicates better crystallinity.
● Thermal shock resistance
Thermal shock resistance refers to the resistance of coke products to rupture when subjected to thermal shock of sudden rise to high temperature or rapid cooling from high temperature. Especially for high-quality petroleum coke, such as needle coke, has better thermal shock resistance, so it has higher use value.
● Granularity
Granularity refers to the content of powder coke and lump coke (usable coke) in coke. Most of the powder coke is crushed by mechanical action, such as extrusion and friction during decoking and storage and transportation, so the content of powder coke is also manifestation of mechanical strength. Coke with more lump coke and less powder coke has higher use value.
3. အနှစ်ချုပ်
Petroleum coke is an important industrial raw material with a wide range of applications, such as in the power, metallurgy, and chemical industries. High-quality petroleum coke can be used as high-quality fuel for thermal power plants and it is an indispensable reducing agent in the production of steel and aluminum. In actual applications, petroleum coke needs to be crushed and graded to ensure that the fineness and purity meet application requirements. Roller mill and air classifier can achieve the grinding and classifying of petroleum coke.
