Activated Alumina Desiccant , High Purity Aluminum Oxide For Catalyst Carrier
Descrition:
Activated alumina has many advantages,such as, good adsorption, strong catalytic activity, porosity, high dispersity and large specific surface. It can be used as absorbent, desiccant and catalyst carrier. It is also a kinf of trace water desiccant and the pole-moleculae absorbent, according to the absorbed molecule polarization, the attachment force is strong for water, oxide, acetic acid, alkali ect.
Activated alumina defluorinates just as the anion exchange resin, but the selectivity is much strong. The defluorination effect of the activated alumina is good. The capacity is stable. It has high strength, low abrasion, no soften in water, no expansion, no powdery no crack. It can widely used in the deep drying of cracked gas, ethylene and propylene, hydrogen-generation, air seperation, instrument air drying and fluorine treatment for H2O2, alos in the absorbing pollution material, such as H2S, SO2, HF and paraffin in the waste gas, especially in the drinking water defluorination.
