Spherical green silicon carbide carrier

Green silicon carbide carrier
Detailed introduction () pure silicon carbide maleic anhydride catalyst, pyridine catalyst, petrochemical catalyst inert carrier is a combination of the catalyst developed by the Beijing Research Institute of Chemical Industry and the B catalyst developed by Tianjin Tianhuan Fine Chemical Research Institute, Wuhan The modern new catalytic carrier product developed by the cyanopyridine catalyst of the Catalyst Factory of the University Institute of Chemical Engineering has effectively overcome the shortcomings of large bed resistance and high operating hot spot temperature. It mainly uses green silicon carbide as the main material and is scientifically formulated and reasonably selected to be partially inert. Kaolin refractory material is added with a small amount of various auxiliary materials and additives, and is sintered through scientific formula and special high-temperature environment. It is in the shape of a ring carrier with good thermal conductivity, reduced bed resistance, easy to increase air volume, low hot spot temperature, and hot spot distribution. balanced. , Scope of application: It is widely used as a carrier for various precious metal catalysts in devices such as maleic anhydride, pyridine, fumaric acid, petrochemical n-alkane isomerization, low-temperature desulfurization, tail gas purification, and linear alkanes isomerization. , Product Performance Characteristics This product has excellent physical and chemical properties, corrosion resistance, high strength, low specific surface, high wear resistance, good thermal conductivity, low thermal expansion coefficient, strong thermal reducibility, high load capacity, small bed resistance and It has a long service life and is not easy to interact with active ingredients. It is suitable for use in some harsh reaction conditions such as high temperature and strong corrosion. When used under high temperature conditions, it will not produce volatilization and cause the active components of the catalyst to burn and agglomerate. This carrier is the best carrier choice for the production of special catalyst products. . , Main technical indicators of the product. Physical and chemical performance project indicators.
