性狀：
　  矽鋁膠外觀呈微黃色，化學分子式mSiO2.nAl2O3.xH2O。化學性質穩定、不燃燒、除強堿和氫氟酸外不溶于任何溶劑。細孔矽鋁膠和細孔矽膠相比低濕度吸附量相當，但高濕度吸附量比細孔矽膠高6—10%，熱穩定性比細孔矽膠（200℃）高150℃以上，非常适宜作變溫吸附、分離劑。
用途：
主要用于天然脫水、變溫吸附分離輕烴等。也可用作石油行業的催化劑及催化劑載體、工業用幹燥劑、液體吸附劑及氣體分離等。

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.。
