Introduction to Calcined Petroleum Coke

Calcined petroleum coke (CPC) is the byproduct obtained from the coker unit in a crude oil refinery. lt is primarilyused to make anodes for the aluminum, steel, and titanium smelting industry.

Petroleum coke manufactured by delayed coking of residues obtained from crude oil distillation units of oil refineries is called green or raw petroleum coke. The said green or raw petroleum coke calcined at a temperature 12000 centigrade to 13000 centigrade is known as calcined petroleum coke.

Calcinedoetroleum coke is also used as a feedstock for a wide range of the products such as aluminum, paints, coatings, andcolorings, etc. Calcined petroleum coke is a black-colored solid material primarily comprises of carbon, sulfurmetals, and nonvolatile inorganic compounds. lt offers several advantages such as safe handling, transportationand storage with low toxicity.

Properties of Calcined Petroleum Coke

After high-temperature treatment, the high-temperature resistance of calcined petroleum coke is significantly improved. It can maintain the stability of the structure at extremely high temperatures and is not easy to soften or melt, so it has good stability in high temperature environments.

The hardness and wear resistance of calcined petroleum coke are enhanced. It has high compressive strength and wear resistance, can withstand high pressure and friction, and reduces wear and the generation of wear products.

The calcination process further reduces the volatile matter in petroleum coke. Volatile matter refers to the substances that volatilize from petroleum coke during the heating process. Reducing volatile matter can improve the thermal stability and calorific value of petroleum coke, and reduce emissions and energy loss during combustion.

The true density of calcined petroleum coke increases, that is, the mass per unit volume increases. High true density means more carbon mass is contained in the petroleum coke, improving its electrical and thermal conductivity properties.

Calcined petroleum coke has good electrical conductivity properties, making it ideal for making electrodes and conductive materials. It conducts electric current efficiently and is used in electric arc furnace smelting, battery production and other electrochemical applications.

Calcination helps to increase the degree of graphitization of petroleum coke, that is, the perfection of the graphite structure. The increase in the degree of graphitization increases the proportion of graphite structure of petroleum coke and improves its electrical conductivity, mechanical strength and thermal conductivity.

What projects can Calcined Petroleum Coke provide services for?

For Aluminum Electrolysis:

Calcined petroleum coke plays a key role in the aluminum electrolysis process. As the cathode material of aluminum electrolysis cells, it has unique properties and functions.

Because calcined petroleum coke has low resistivity and high electrical conductivity, it is able to efficiently conduct large amounts of electrical current. This is important for efficient aluminum electrolysis, as large amounts of electrical energy are required to reduce aluminum ions to metallic aluminum during the electrolysis process.

In addition, calcined petroleum coke has excellent high temperature resistance. During the aluminum electrolysis process, the temperature inside the electrolytic cell is very high, and calcined petroleum coke is able to withstand these extreme temperature conditions without failure. This high temperature resistance ensures the stability and durability of the calcined petroleum coke throughout the electrolysis process.

Choosing the Optimal CPC for Your Aluminum

For Steelmaking:

Calcined petroleum coke is an important material in steel smelting and is widely used as a reducing agent and fuel. It plays a key role in blast furnace smelting and electric arc furnace smelting processes, helping to remove oxides, reduce metal ores, and provide fuel with high calorific value.

By adding calcined petroleum coke, the iron oxide in the iron ore can be effectively reduced and converted into molten iron. Calcined petroleum coke is also used as a fuel in the steel smelting process, and the presence of calcined petroleum coke also helps remove oxides from metal ores. By adding calcined petroleum coke as a flux, the mixing and reaction during the smelting process can be promoted, and the smelting efficiency and product uniformity can be improved.

Choosing the Optimal CPC for Your Steel

Graphite Electrode Manufacturing:

Calcined petroleum coke plays an important role in the production of carbon products. It is a key raw material for the manufacture of carbon-based products such as graphite electrodes and carbon fibers. Calcined petroleum coke has high electrical conductivity and graphitization, and is widely used in the manufacture of batteries, lithium-ion batteries, graphite materials and other carbon-based products.

Calcined petroleum coke is one of the main raw materials in the manufacturing process of graphite electrodes. Graphite electrodes are key components used in various electric arc furnaces (such as steel smelting, electric furnace smelting, etc.) and are also widely used in industrial processes such as aluminum electrolysis and synthetic gas production. Calcined petroleum coke has high electrical conductivity and a degree of graphitization, making it ideal for manufacturing high-performance graphite electrodes. Through the processing and shaping of calcined petroleum coke, graphite electrodes with good electrical conductivity, high strength and high temperature resistance can be produced.
