性狀
變壓吸附硅膠外觀呈透明或半透明玻璃狀，化學(xué)分子式為mSiO2．nH2O, 化學(xué)性質(zhì)穩(wěn)定，無毒無味，與細(xì)孔硅膠有相似之處，但選擇性吸附能力優(yōu)于細(xì)孔硅膠。變壓吸附硅膠主要具有吸附快、脫附亦快的特點(diǎn)。
用途
變壓吸附是一項(xiàng)氣體分離及凈化的高新技術(shù)，變壓吸附硅膠主要用于二氧化碳?xì)怏w的回收、分離及凈化，用于合成氨工業(yè)、食品飲料加工工業(yè)等制取二氧化碳，亦可用于干燥、防潮及有機(jī)產(chǎn)品的脫水精制等。

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.
