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 *7% water resistant silica alumina gel, 0.5% ~ 8%
fine-pored silica alumina gel.
*7% Silica Alumina Gel
*7% 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
*0% 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~*0% at high relative humidity, and thermal
stability is **0 ℃ higher than fine-pored silica gel (**0 ℃), 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.
