硅铝胶
硅胶系列 2018-08-28 11:26
性状
   硅铝胶外观呈微黄色,化学分子式mSiO2.nAl2O3.xH2O。化学性质稳定、不燃烧、除强碱和氢氟酸外不溶于任何溶剂。细孔硅铝胶和细孔硅胶相比低湿度吸附量相当,但高湿度吸附量比细孔硅胶高6—10%,热稳定性比细孔硅胶(200℃)高150℃以上,非常适宜作变温吸附、分离剂。
用途
主要用于天然脱水、变温吸附分离轻烃等。也可用作石油行业的催化剂及催化剂载体、工业用干燥剂、液体吸附剂及气体分离等。

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.。
