Molecular formula: mSiO2·nAl2O3·xH2O
Silica alumina gel, which is a kind of special products formed by adding a certain amount of alumina in fine-pored silica gel, different aluminum oxide content has different performance. Chemxin has 17% water resistant silica alumina gel, 0.5% ~ 8% fine-pored silica alumina gel.
17% silica alumina gel is a kind of fine-pored water-resistant silica alumina gel, generally used as a protective layer for fine-pored silica gel and fine-pored silica alumina gel. It can also be used alone under a high content of free water (liquid water). Although operating system contains liquid water, this product still can achieve a lower dew point.
Mainly used for drying air in the process of air separation; acetylene adsorption in the production process of liquid ammonia and liquid nitrogen; compressed air drying and all kinds of industrial gases drying; as liquid adsorbent and catalyst carrier in the petrochemical industry, electric utility and brewing; as protective layer for common silica gel and silica alumina gel.
