Silica Alumina Gel
Characteristics
Color: faint yellow.
Chemical molecular formula: SiO2.nAl2O3.xH2O.
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-ported silica gel. Its thermal stability is over 150 higher than that of fine-pored silica gel (200). Ideally suited for use as adsorbent and Variable-temperature adsorbent.
Use
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..
