Variable Pressure Absorption Silica Gel

Variable Pressure Absorption Silica Gel

Variable pressure adsorption silica gel istransparent or semitransparent glassy in substance. Its chemical molecular formula ismSiO₂．nH₂O with stable chemical property, no toxin and no special odor, possessing somesimilar characteristics with fine-pored silica gel, while its selectiveabsorbing performance is better than fine-pored silica gel, possessing fastabsorption and dehydration.

Application
Pressureswing adsorption (PSA) is one kind of high-tech to separate and purify air;mainly used for recycle, separating and purifying carbon dioxide in syntheticammonia industry, food, beverage processing industry, as well as drying, dampproofing and dehydration of organic products, etc.

Characteristics
By adopting special adsorbent production techniques, we canprecisely control the pore diameter and pore volume ofthe silica gel, so as to change its superficial physical properties. Thisprovides the adsorbent silica gel with advantages like huge adsorption volume,fast adsorption and desorption speed, strongadsorbent selectivity and high separation coefficient.
