Activated Alumina

For the activated alumina, there are such varied merits, for instance, the properties of absorption, catalytic activation, porous, higher dispersion, and larger specific surface areas etc. It adapts to the drying of many gases and liquids, Further, it can be applied to as the absorbents, drying agents, catalysts, and carriers during many reactions in the fields of the petroleum, chemical fertilizer, and chemical industry.
For the activated alumina, there are γ and X-P assortments according to the inner main crystal phase.
In accordance with the usage, it can be divided into the activated alumina absorbent, the activated alumina drying agent, and the activated alumina catalyst carrier.
Activated 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.
