Application
Depending on its quality, petroleum coke can be used in industries such as graphite, smelting and chemical industry, etc
Petroleum coke, as a byproduct of petroleum, is produced in the process of petroleum processing, that is, the crude oil is distilled to separate light and heavy oil, and the heavy oil is converted into petroleum coke by hot cracking. If petroleum coke can be obtained directly from petroleum processing, then the petroleum coke is raw coke or ordinary coke. Petroleum coke has irregular shape, dark gray or black, porous structure and metallic luster.
Request a quoteLow-sulfur petroleum coke is mainly used to make electrodes. In downstream applications, it is basically distinguished by the level of sulfur content. Low-sulfur petroleum coke is mainly used to produce graphite electrodes, lithium battery negative electrodes, and high-end pre-baked anodes, which are used as important materials in the steelmaking industry. In the case of graphite electrodes for steelmaking or anode pastes (melting electrodes) for aluminum and magnesium production, in order to adapt the petroleum coke (green coke) to the requirements, the green coke must be calcined. The calcination temperature is generally around 1300 ° C, the purpose is to remove the volatile components of petroleum coke as much as possible. In this way, the hydrogen content of the recycled petroleum coke can be reduced, and the degree of graphitization of the petroleum coke can be improved, thereby improving the high temperature strength and heat resistance of the graphite electrode, and improving the electrical conductivity of the graphite electrode.
Most of the petroleum coke currently produced by the Franli plant is low-sulfur petroleum coke, which is mainly used for aluminum smelting, graphite and carbon products. In the low-sulfur petroleum coke field, graphite electrodes and fuel will account for 58% and 23% respectively in 2021. , the proportion of lithium battery anodes and graphite electrodes with greater future demand potential is only 2% and 1%.
The Importance of Low Sulfur petroleum coke
(1) The trend of replacing long-term processes with short steel processes has been established, the proportion of electric furnaces will continue to increase, and the demand for graphite electrodes will increase. Although the proportion of ordinary power electrodes has decreased, the absolute amount will continue to grow;
(2) Low-sulfur petroleum coke is mainly used for medium and low-end anode materials. New energy vehicles continue to develop rapidly. In the future, both high-end and low-end routes will be given equal attention. The demand for needle coke and low-sulfur petroleum coke may grow rapidly together; The development of power energy storage has entered the fast lane, and the demand for low-end anode materials has great potential, which may further open up the growth space of petroleum coke.
(3) In the future, the demand in the field of energy conservation and environmental protection is still strong, the negative electrode demand potential is large, and the supply growth is limited. Due to the high impurities such as sulfur, it is difficult to graphitize medium-sulfur coke, and the replacement and demand for petroleum coke are gradually increasing.
Other Applications for Low Sulfur petroleum coke
(1) Fuel: Low-sulfur petroleum coke fuel has a high calorific value of 35.5MJ/kg, which can replace coal tar, natural gas, and heavy oil for burning in glass melting furnaces, with outstanding features of high efficiency and low cost.
(2) Glass: Compared with other fuels, petroleum coke powder has poor combustion stability. When the unburned petroleum coke powder is mixed into the glass liquid, it will have a serious impact on the quality of the glass, such as yellow glass or green glass, which will affect the whiteness of the glass.The ash of petroleum coke powder contains iron, vanadium and other elements, which fall into the glass liquid after combustion, and the flame atmosphere is partial reduction, which makes the color of the glass burning petroleum coke darker, which will obviously reduce the light transmittance of the glass.
The demand for low-sulfur petroleum coke in major metallurgical and industrial industries has greatly expanded, and the demand for lithium battery anodes has great potential. The expansion of the low-sulfur petroleum coke gap will intensify resource competition. The Franli plant is also producing high-quality low-sulfur petroleum coke in large quantities. The sulfur content of petroleum coke mainly depends on the raw material. The coking process has little effect on the sulfur content of petroleum coke, while the quality of crude oil is related to the place of origin. The Franli plant uses high-quality raw materials. Precision machining to form low-sulfur petroleum coke. Customers in need can consult us and we will provide preferential prices.
