Product: Macro-pored Micro-spherical Silica Gel
CAS NO: 112926-00-8
Molecular formula: SiO2.nH2O
Properties:
White, transparent or translucent pellets. Average pore diameter 8.0-12.0nm. Specific surface area 300-600 m2/g. Pore volume 0.8-1.1 ml/g. Specific heat 0.92 KJ/kg, ºC. Thermal conductivity 0.167 KJ/m.hr. ºC. Internally well-distributed micro-pored structure. Physically and chemically stable. Good thermal stability, high mechanical strength.
Application:
Used as catalyst or catalyst carrier in the manufacturing of the important industrial products, such as cyanuramide, benzene anhydride, maleic acid anhydride, butadiene rubber, acrylic nitrite, etc. It is also widely used for highly refining petrochemical products by adsorbing aromatic hydrocarbon. It may also be used for elimination multivalent poisonous elements in water through ion exchanging process.
