Activated Alumina for Desiccant

Activated alumina ball, to be used as absorbent,desiccant and catalyst carrier. It is also a kind of trace water desiccant and pole-mlecule absorbent, the attachment force is strong for water, oxide, acetic acid,alkali etc.

Activated alumina defluorinates jut as the anion exchange resin, but the selectivity is much strong. The defluorina effect of the activated alumina is good. The capacity is stable. It has high strength, low abrasion, no softent in the water, no expansion, no powdery no crack. It can widely used in te deep drying of cracked gas, ethylene andpropylene, hydrogen-generation, air seperation, insrument air drying and fluorine treatment for H2O2, also in the absorbing pollution material, such as H2S,SO2,HF and paraffin in the waste gas, especially in the drinking water defluorination.
