Activated alumina
 
　Products picture

actiove alumiona

　　In α—β phase activated alumina, there are much 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.
　　Actived alumina defluorinates just as the anion exchange resin, but the selectivity is much strong. The defluorination effect of the actived alumina is good. The capacity is stable, the absorbed fluorine is 6400 g/m3. 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 separation、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.
