Calcined Petroleum Coke /Cpc

Calcined petroleum coke is a product obtained by calcining petroleum coke at high temperatures. Petroleum coke is a by-product of the petroleum refining process. It appears as a black or dark gray hard solid and is porous. It is composed of tiny graphite crystals forming granular, columnar or needle-shaped carbon bodies.

Calcined petroleum coke has the advantages of low ash content, high carbon content, electrical conductivity, thermal conductivity, good chemical stability and thermal stability. It is the main material for the production of aluminum anodes and graphite products.

It can be used as a carburizer in steel-making furnaces and as a reducing agent in silicon carbide, industrial silicon, and yellow phosphorus electric furnaces.

• Improve the density and mechanical strength of raw materials: After calcination treatment, the volatile components in petroleum coke are eliminated and the volume shrinks, causing its density to increase and its strength to increase. This increase in density and mechanical strength helps improve the stability and durability of petroleum coke during subsequent processing and use.
• Improved electrical conductivity: The calcination process reduces the resistivity of petroleum coke, thereby improving its electrical conductivity. This is because calcination eliminates volatile organic matter that hinders conductivity. At the same time, the molecular structure also changes and the carbon network increases, which improves the conductivity of petroleum coke.
• Improve antioxidant properties: During the calcination process, impurities such as hydrogen, oxygen, and sulfur in petroleum coke are discharged through the pyrolysis and polymerization processes, the chemical activity decreases, and the physical and chemical properties tend to be stable, thereby improving its antioxidant properties.
• Improve chemical stability: Calcination causes the internal molecular structure of petroleum coke to change, the graphite crystallites grow, the true density increases, and the chemical stability is enhanced. This increased chemical stability helps petroleum coke maintain stable performance in a variety of chemical environments.
• Energy saving and environmental protection: During the calcination process, the gas generated can be used to heat the coke oven itself, which is beneficial to the comprehensive utilization of energy and environmental protection. This recycling method helps reduce energy consumption and environmental pollution.
