Coarse pore silica gel 20-40 mesh microsphere particle catalyst carrier

The appearance of coarse pore microsphere silica gel is white transparent or translucent, and its interior has uniform micropore structure, stable physical and chemical properties, good thermal stability, high mechanical strength. Coarse pore microsphere silica gel is used as catalyst carrier in the production of melamine, anhydride, maleic anhydride, butadiene rubber, acrylonitrile and other important industrial products. It is also widely used in the refining of petrochemical products to remove aromatics. It can also be used in the selective adsorption separation of organic gas and liquid and the removal of polyvalent harmful elements in water by ion exchange.
