性狀
　 變壓吸附硅膠外觀呈透明或半透明玻璃狀，化學分子式爲mSiO2．nH2O, 化學性質穩定，無毒無味，與細孔硅膠有相似之處，但選擇性吸附能力優於細孔硅膠。變壓吸附硅膠主要具有吸附快、脫附亦快的特點。用途
　　變壓吸附是一項氣體分離及淨化的高新技術，變壓吸附硅膠主要用於二氧化碳氣體的回收、分離及淨化，用於合成氨工業、食品飲料加工工業等製取二氧化碳，亦可用於乾燥、防潮及有機產品的脫水精製等。

Silica gel for variable-pressure adsorption
Characteristics：
Color: transparent or translucent, glass-like.
Chemical molecular formula: SiO2.nH2O.
Chemically stable, Nontoxic, tasteless, Similar to fine-pored silica gel.
Its selective adsorptive capability is higher than fine-pored silica gel. 
Fast adsorption,quick deadsorpton.

Use：
Variable-pressure adsorption（PSA） is a kind of new high-technology used for gas separation and purifying. Mainly used for the recovery, separation and purifying of carbon dioxide gas. It is used for preparation of carbon dioxide in synthetic ammonia industry, food & beverage processing industry, etc. It may also be used for drying, moisture absorption as well as dewatering of organic products.
