At present, the production methods of the polysilicon industry mainly include the silane method and the modified Siemens method. The modified Siemens method and the silane method mainly produce solar-grade/electronic-grade crystalline silicon. The silane method is to pass silane into a fluidized bed with polycrystalline silicon seeds as fluidized particles, so that silane is cracked […]

Nuclear reactors in power plants use a large amount of fission nuclear fuel uranium. There are mainly three isotopes in the nature: U-238, U-235 and U-234, of which fissionable U-235 is currently the main nuclear fuel used now. However, the characteristics of natural uranium ore are low grade, scattered ore body and small scale in […]

Catalytic hydrogenation technology is the core technology in medicine, fine chemical industry, and other organic synthesis. In the application of catalytic hydrogenation technology, noble metal catalysts with relatively high catalyst activity are mainly used, such as Palladium-carbon catalysts, Raney nickel catalysts, etc. At this stage, precious metal catalysts used in industrial production and research work […]

In the production of organic silicon monomer raw materials, as the end-product, high-purity dichloromethane/ DCM/ methylene chloride is very important. However, the production of DCM often contains a certain amount of impurity calcium chloride. Shinkai’s metal filter with sintered powder filter elements can perfectly filter and purify the DCM to 2ppm. In October, we just […]

Modified starch is made from natural starch by chemical or physical modification. Natural starch is a kind of natural polymer made from glucose condensation. It is a kind of renewable material with the most abundant source in nature. It can be degraded and is environmentally friendly. As a food additive, modified starch has the advantages […]

With the development of the World’s industrial economy and population explosion, human beings are facing more and more serious environmental pollution problems, especially water pollution. In recent years, electrocatalytic oxidation technology has attracted great attention because of its great advantages in removing COD from industrial wastewater. The key point of electrocatalytic technology is to develop […]

The Tokyo Olympic Games, held one year late, have made many sports fans look forward to it for a long time, and the materials used to implement the principle of 3R hosting the Olympic Games are even more refreshing. Such as p polyurethane weightlifting equipment, running track, recycled plastic podium, etc. The green organic synthesis […]

July 12, the reporter learns from Nanjing Shinkai Filter Co., Ltd that their hot gas filter system with metal filters has been successfully applied in polysilicon enterprises. That indicates the technology has been successfully applied in the polysilicon industry after its successful application in the lithium battery, graphene and other industries. This is of great […]

Gasoline, Kerosene and diesel are the important fuels, all those are sourcing from Petroleum Refining. Petroleum is usually named as “Blood of Industry”, but it is hardly used as above fuel directly, it must be re-processed to gasoline, kerosene or diesel for further human using. FCC Fluid catalytic cracking is the most important convert method […]

In our previous article that paid attention to hot gas filtration in refining and chemical plant. Because of the hot gas filter´s excellent performance in extreme special conditions (such as high temperature, high pressure, toxic gas, etc.). As a result, this filter has been warmly welcomed in refineries and has been used in many refining […]
