What is the use of petroleum calcined coke and what is the use of petroleum coke

Calcined petroleum coke is mainly used for pre-baked anodes and cathodes for electrolytic aluminum, carburizers and graphite electrodes for production in metallurgical and iron and steel industries, and carbon electrodes for industrial silicon, yellow phosphorus and ferroalloys. Therefore, both electrolytic aluminum plants, independent carbon plants and oil refineries are more concerned about the progress and development of petroleum coke calcination technology.

Seeing that calcined petroleum coke has so many effects, it is necessary to vigorously develop new production skills to further improve the use of calcined petroleum coke. In particular, there is still a lot of room for technical development in the calcining furnace for the domestic production of calcined petroleum coke, and in-depth research should be focused on the application of new materials, the development of high-quality silica bricks, multi-channel waste heat resources, the improvement of automation, scientific oven and standardized operation, etc., so that the use rate of calcined petroleum coke is higher, the use effect is better, and the smelting furnace should develop a long life, high production capacity, intelligent environmental protection, and economical industrial furnace. In particular, it is necessary to pay attention to the combination of numerical simulation technology and production practice, and scientifically improve the quality and technical problems of calcined petroleum coke in China, so as to further reduce production costs and improve production efficiency.

Prebaked anodes and anode pastes used in electrolytic aluminum, carbon industry production of carburizers, graphite electrodes, smelting of industrial silicon, fuels, etc.

It should be called asphalt and is used to build roads, etc.

Petroleum coke. It is a product that is transformed into a product after distillation separates light and heavy oil, and then through the process of hot cracking, from the appearance, coke is irregular in shape, black blocks (or particles) of different sizes, with metallic luster, coke particles have a porous structure, and the main element composition is carbon.

Petroleum coke can be used in graphite-making, smelting, and chemical industries depending on its quality, among which:

Low-sulphur, high-quality cooked coke, such as needle coke.

It is mainly used in the manufacture of ultra-high power graphite electrodes.

and some special carbon products, needle coke is an important material for the development of new electric furnace steelmaking technology in the steelmaking industry;

Medium sulfur, ordinary cooked coke, a large number of used in aluminum smelting;

High-sulfur, ordinary green coke is used in chemical production, such as the manufacture of calcium carbide and silicon carbide.

It is also used as a fuel for metal casting.

Most of the petroleum coke produced in China is low-sulfur coke, which is mainly used for aluminum smelting and graphite. In addition, it is mainly used for the preparation of carbon products, such as graphite electrodes and anode arcs, to provide steelmaking, non-ferrous metals and aluminum; Preparation of silicon carbide products, such as various grinding wheels and sand skins.

sandpaper, etc.; Produce commercial calcium carbide for the production of synthetic fibers and acetylene.

and other products; It can also be used as fuel, but when it is used as fuel, it needs to use a graded impact mill for ultrafine grinding, and it can only be burned after being made into coke powder by JZC-1250 equipment.

With the rapid development of China's cement, electrolytic silver, iron and steel and thermal power industries, the demand for low-sulfur petroleum coke has increased sharply, and with the increasingly strict environmental protection policies, the use of high-sulfur petroleum coke has been greatly limited. Therefore, China's petroleum coke market will face a shortage of low-sulfur petroleum coke and a serious surplus of high-sulfur petroleum coke in the future.

It is divided into low sulfur, medium sulfur and high sulfur calcined coke, and the use is different.

The use of low-sulfur calcined coke: as a thermal insulation material and filler material for the manufacture of graphite electrodes and special carbon products; As a carburizer or reducing agent.

It is used in the metallurgical casting industry, as well as in the titanium industry;

The use of medium sulfur calcined coke: generally used for aluminum, mainly used for electrolytic aluminum.

pre-baked anodes and cathodes used;

The use of high-sulfur calcined coke: it can be used in chemical production, silicon carbide.

or used as fuel for metal fabrication, glass factories, etc.;

The difference between calcined coke and petroleum coke is one: appearance.

Calcined coke: From the appearance, calcined coke is a black block with irregular shape and different sizes, with strong metallic luster, and the pores of carbon particles are more transparent after calcination;

Petroleum coke: Compared with calcined coke, there is little difference between the two in terms of shape, but compared with calcined coke, the metallic luster of petroleum coke is weak, the surface of the particles is not dry after calcined, and the pores are not transparent after calcined coke; The difference between calcined coke and petroleum coke is two: production process and index.

Petroleum coke: Petroleum coke is a product that is converted into a product after the separation of light and heavy oil by elimination and distillation, and then the heavy oil is converted into a process of hot cracking, the main element composition is carbon, and the rest is hydrogen, nitrogen, sulfur and metal elements and some mineral impurities (water, ash, etc.).

Calcined coke: calcined coke is made of petroleum coke, raw material calcination is an important process in the carbon production process, in the calcination process, carbonaceous raw material structure and element composition will undergo a series of changes, through calcination can remove most of the volatile matter and water in the raw material, with the elimination of most volatile matter and water, carbon volume shrinkage, density increase, mechanical strength will also become stronger, so as to reduce the secondary shrinkage of the product during calcination, the more sufficient the calcination of raw materials, the more beneficial to product quality.

The third difference between calcined coke and petroleum coke: use.

Calcined coke: Calcined coke is mainly used for prebaked anodes and cathodes used in electrolytic aluminum, carburizers for metallurgical steel industry production, graphite electrodes, carbon electrodes for industrial silicon and ferroalloys, etc.

The needle coke in petroleum coke is mainly used for high-power graphite electrodes, and the seabeard coke is mainly used in the steelmaking industry and carbon industry.

The difference between calcined coke and petroleum coke is that in terms of appearance, the former leaks out of the service is irregular in shape, and the black block metal of different sizes has a strong sense of guanze, while the latter is not much different in shape and has a darker luster.

The difference between and petroleum coke is in **, these two are like socks and regrets, Bizhou has its own words, and the words of teaching should indicate that her maturity and his differentiation should be different from the fixed point, and the law is also different.

Calcined coke: From the appearance, calcined coke is a black block with irregular shape and different sizes, with strong metallic luster, and the pores of carbon particles are more transparent after calcination with cores;

Petroleum coke: Compared with calcined hand coke, there is little difference between the two in terms of shape, but compared with calcined coke, the metallic luster of petroleum coke is weak, the surface of the particles is not dry after calcining, and the pores are not transparent after calcining;

Summary. <>

Hello, thank you for your patience, calcined petroleum coke (CPC) and calcined petroleum coke (CPC) are two different forms of the same substance obtained under different process parameters. The specific differences are as follows:1
