Activated alumina, as a porous form of granular alumina, has a high surface area, can effectively adsorb liquids and gases, and can also be used as a desiccant and catalyst carrier. At the same time, it is also determined according to the polarity of the adsorbed substance, which has a strong affinity for water, oxide, acetic acid, alkali, etc., and is a kind of micro-water depth desiccant and an adsorbent for adsorbing polar molecules.
Features/Advantages
Activated alumina has high strength, low wear, water immersion unchanged soft, no expansion, no powder, no rupture.
Application
It can be widely used in petroleum cracking gas, ethylene, propylene gas depth drying and air separation equipment, instrument drying machine drying, but also can remove sulfur gas hydrogen, sulfur dioxide, hydrogen fluoride, hydrocarbons and other pollutants in the exhaust gas, especially suitable for pressure swing adsorption gas drying treatment.
