Activated alumina adsorbent

Activated alumina has many capillary channels and large surface area, which can be used as adsorbent, desiccant and catalyst. At the same time also according to the polarity of adsorbents to determine, to water, oxide, acetic acid, alkali and other strong affinity, is a moisture depth desiccant, but also adsorption of polar molecules adsorbent.

● defluoridation of activated alumina is similar to that of anion exchange resin, but the selective anion resin of fluoride ion is large. Activated alumina adsorption defluorination effect is good, stable capacity, per cubic meter activated alumina fluoride absorption 6400 grams. This product has high strength, low wear, water immersion soft, no expansion, no powder, no rupture. It can be widely used in the deep drying of petroleum cracking gas, ethylene propylene gas and the drying of hydrogen production, air separation device, instrument air dryer, fluoride treatment in hydrogen peroxide can also remove sulfur gas hydrogen, sulfur dioxide, hydrogen fluoride, hydrocarbons and other pollutants in the exhaust gas, especially suitable for the defluoridation of water containing fluorine.
