Activated alumina is a porous, highly dispersed solid material with a large surface area, and its microporous surface has the properties required for catalysis, such as adsorption performance, surface activity, excellent thermal stability, etc., so it is widely used. Widely used as catalysts and catalyst supports for chemical reactions. The spherical activated alumina pressure swing oil adsorbent is white spherical porous particles. The activated alumina has uniform particle size, smooth surface, high mechanical strength, strong hygroscopicity, and does not swell or crack after absorbing water. water, ethanol. Activated alumina is a high-efficiency desiccant for deep drying of trace water, which is very suitable for heatless regeneration devices.

Normal activated alumina:
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 and pro-pylene, hydrogen-generation, air seperation, instrument air drying and fluori-ne treatment for H2-O2, alos in the absorbing pollution material, such as H2S, SO2, HF and paraffin in the waste gas, especially in the drinking water defluorination.

A white or slightly red particle, ball-shaped or roll-shaped, activated alumina is insoluble in water and organic solvent, soluble in strong acids and alkalis, odorless, tasteless and non-toxic.
1) Catalyst for recovering sulfur in the petrochemical industry
2) Excellent defluorination agent for drinking water and for recycling alkyl-hydrocarbon in alkylbenzene production
3) Reclaiming agent for de-acidic in transformer oil, and de-arsenic agent in the Acid industry
4) Adsorbent in the production of hy-drogen peroxide solution
5) Catalyst for polyhydro-ammonia by substituting silica gel with ball-shaped product
6) Desiccator and purifying agent.
