Activated alumina has many micro-paths, so the specific surface is large.It can be used as absorbent, desiccant and catalyst carrier. It is also a kind of trace water desiccant and the pole-molecule 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, hydrogen-generation, air seperation, instrument air in the absorbing pollution material, such as H2S, SO2, HF and paraffin in the waste gas, especially in the drinking water defluorination.
