What is petroleum coke used for?

Petroleum coke (PETroleum coke) is a product obtained by distilling crude oil through distillation to separate light and heavy oil, and then heavy oil undergoing thermal cracking.

From the appearance of petroleum coke, coke is irregularly shaped, black lumps (or particles) of various sizes, metallic luster, and coke particles have a porous structure. The main elemental composition is carbon, which accounts for 80wt% The English abbreviation of Weight means the weight percentage content. 5WT% is equivalent to more than 50,000 PPM (PPM is in millions of content), and the rest are hydrogen, oxygen, nitrogen, sulfur and metal elements.

Petroleum coke has its unique physical, chemical and mechanical properties. It is a non-volatile carbon that generates heat, and volatiles and mineral impurities (sulfur, metal compounds, water, ash, etc.) determine the chemical properties of coke.

Petroleum coke can be used in graphite, smelting and chemical industries depending on its quality.
 
Low-sulfur, high-quality cooked coke, such as needle coke, is mainly used to manufacture ultra-high power graphite electrodes and some special carbon products; needle coke is an important material for the development of new technologies for electric furnace steelmaking in the steelmaking industry. Medium sulfur, ordinary cooked coke, a large amount is used for aluminum smelting. High sulfur and common raw coke are used in chemical production, such as calcium carbide, silicon carbide, etc., and also used as 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 production. Graphite electrodes are also mainly used to make carbon products, such as graphite electrodes, anode arcs, and steel, non-ferrous metals, and aluminum. Preparation of silicon carbide products, such as various wheels, sandpaper, sandpaper and so on. Preparation of commercial calcium carbide for the production of synthetic fibers, acetylene and other products. It can also be used as fuel, but when it is used for fuel, it needs to use a graded impact mill for ultra-fine crushing. After making coke powder through JZC-1250 equipment, it can be combusted. The main use of coke powder as fuel is glass plants, coal Pulp mill and so on.

The above is a brief answer to the questions about the use of petroleum coke and what is petroleum coke. The use of petroleum coke is more reflected in the chemical industry, so if you want to learn more, please visit www.sino-stargroup.com

High carbon silicon production process In the process of smelting metal silicon, there is a case where the electrodes are not uniformly heated in the furnace. As a result, the furnace bottom fails to reach the optimum temperature required to produce metal silicon. A small amount of raw materials such as silica and carbon at the bottom did not fully react. After a long period of accumulation under high temperature conditions, it forms a block on the bottom of the furnace. These large (stable traits) chunks are broken and screened, which is what we often call   high carbon silicon . High carbon silicon characteristics and uses Current market Alloys for converters have not been adjusted for a long time. The structure of traditional alloys is relatively simple. Q195 and Q235 steels adopt Mnsi+FeSi+SiAiCaBa+Sic+recarboration process. HRB335 and HRB400 steel grades adopt MnSi+Fesi+AiSi+ recarburizer production process. The traditional silicon-manganese alloy, the m...

Henan star metallurgy (located in anyang city) specializing in silicon metal powder 441, silicon metal powder 553, silicon metal powder 3303 research and production sales, silicon metal price how much money a ton?The company will offer the price according to the content and granularity required by customers at any time. Introduction to silicon metal powder : Silicon metal powder is silicon metal (industrial silicon) after grinding and processing of silicon powder. Metallic silicon, also known as crystalline silicon or industrial silicon, is primarily used as an additive to non-ferrous alloys.Industrial silicones are also used as alloys for demanding silicon steels, deoxidizers for special steels and non-ferrous alloys.After a series of processing processes, industrial silicon can be pulled into a single crystal silicon for use in the electronics industry. Silicon metal property ,Metallic silicon is composed mainly of silicon, so it has similar properties with sil...
