Silica Alumina Gel

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. Yuanying has 17% water resistant silica alumina gel, 0.5% ~ 8% fine-pored silica alumina gel.

17% 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.

When use this product as the protective layer, its dosage is about 20% of the total.

0.5%~8% Silica Alumina Gel

The appearance of 0.5 ~ 8% silica alumina gel is slightly yellow, it has good chemical stability, not burning, not dissolved in any solvent. Comparing with fine-pored silica gel, this product has the same adsorption capacity at low relative humidity, but adsorption capacity exceeds 6~10% at high relative humidity, and thermal stability is 150 ℃ higher than fine-pored silica gel (200 ℃), high above. It is very suitable for temperature swing adsorption, separating agent.

It is mainly used for natural dehydration, and light hydrocarbon separation of temperature swing adsorption (PSA), etc. also can be used for petroleum industrial catalyst and catalyst carrier, industrial desiccant, liquid adsorbent and gas separation, etc.
