For Catalyst
  • Product introduction
  • Product description
  • Video description
  • Because of its small particle size, large specific surface area and high purity, colloidal silica can be widely used in the preparation of catalysts such as mto, alkene, desulphurization and denitrification honeycomb, oil chemical refining, molecular sieve (zeolite), pharmaceutical, ceramic denitration honeycomb and various kinds of carbon, silicon and ketone cracking and catalytic oxidation catalysts. It can also be used as a special carrier material for various organic reaction catalysts, acrylonitrile, phthalic anhydride, drugs and other industries with high impurity content.
