Characteristics

Color:  transparent or translucent, glass-like.

Chemical molecular formula: SiO2.nH2O.

It is  nontoxic and odorless with stable chemical properties.  It is similar to narrow pore  silica gel, but its selective adsorption capability is higher than narrow pore silica gel. Fast adsorption and quick resorption are its typical features.

Pressure Swing Adsorption（PSA） is a kind of high and new  technology silica gel used for gas separation and purification. Mainly used for the recovery, separation and purification of carbon dioxide. It is used in synthetic ammonia industry, food & beverage processing industry, etc. to  extract carbon dioxide.  It also can be used for drying, moisture adsorption as well as dewatering of organic products.
