Description

Macro-pored silica gel

Characteristics

Shape: Pellets Color: white, transparent or translucent.

Average pore diameter: 8.0-12.0nm

Specific surface area: 300-600m2/gPore volume: 0.8-1.1 ml/g.

Specific heat: 0.92KJ/kg.℃

Thermal conductivity: 0.167 KJ/m.hr.℃
Internally well-distributed micro-pored structure.
Physically and chemically stable.
Good thermal stability, High mechanical strength.

Use

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 the selectively adsorptive separation of organic gases and liquids, as well as for eliminating multivalent poisonous elements in water through ion exchanging process
