Coarse-porous microsphere silica gel adsorbent

The appearance of silica gel of porous microspheres is white, transparent or translucent. It has uniform microporous structure, stable physical and chemical properties, good thermal stability and high mechanical strength. The average pore size is 8.0-12.0 nm, the specific surface area is 300-600 m2/g, the pore volume is 0.8-1.1 mL/g, the specific heat is 0.92 KJ/kg. C, and the thermal conductivity is 0.167 KJ/m.hr. C. Purpose:This product is used as catalyst and catalyst carrier in the production of melamine, phthalic anhydride, maleic anhydride, butadiene rubber, acrylonitrile and other important industrial products. It is also widely used in the refinement and removal of aromatic hydrocarbons from petrochemical products. It can also be used in the selective adsorption separation of organic gases and liquids and the removal of polyvalent harmful elements in water by ion exchange. Technical Indicators:
