Activated Alumina for Air Drying

Activated Alumina Activated alumina ball,to be used as absorbent,desiccant and catalyst carrier.It is also a kind of trace water desiccant and pole-molecule absorbent,according to the absorbed molecule polarization,the attachment force is strong for water,oxide,acetic acid,alkali etc. 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, also in the absorbing pollution material, such as H2S, SO2, HF and paraffin in the waste gas, especially in the drinking water defluorination..
