            硅鋁膠
            硅膠系列 2018-08-28 03:26:21
            性狀
               硅鋁膠外觀呈微黃色,化學分子式mSiO2.nAl2O3.xH2O。化學性質穩定、不燃燒、除強鹼和氫氟酸外不溶於任何溶劑。細孔硅鋁膠和細孔硅膠相比低溼度吸附量相當,但高溼度吸附量比細孔硅膠高6—10%,熱穩定性比細孔硅膠(200℃)高150℃以上,非常適宜作變溫吸附、分離劑。
            用途
            主要用於天然脫水、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、工業用乾燥劑、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.。
