Product: Silica Alumina Gel
Molecular formula: SiO2.nAl2O3.xH2O
Properties:
Faint yellow. Chemically stable, flame-resisting. Insoluble in any solvent. In comparison with fine-pored silica gel, the adsorption capacity of fine-pored silica alumina gel is quite the same when used at low relative humidity, (e.g., RH=10%, RH=20%), while its adsorption capacity at high humidity is 6-10% higher than that of fine-pored silica gel. Its thermal stability is over 150 ºC higher than that of fine-pored silica gel (200 ºC). Ideally suited for use as adsorbent and Variable-temperature adsorbent.
Application:
Mainly used for the dewatering of natural gas, adsorption and separation of light hydrocarbon at variable temperatures. It may also be used as catalyst and catalyst carrier in petrochemical industry, industrial drier, liquid adsorbent and gas separator, etc.
