Activated Alumina Used for Drying in Air separation
China Activated Alumina Used for Drying in Air separation, Find details about China Activated Alumina, Adsorbent from Activated Alumina Used for Drying in Air separation
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 propylene, hydrogen-generation, air seperation, instrument air drying and fluorine treatment for H2O2, alos in the absorbing pollution material, such as H2S, SO2, HF and paraffin in the waste gas, especially in the drinking water defluorination.
Molecular formular:
Al2O3. N H2O (0<n≤ 0.8)
Features:
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.
Application:
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 hydrogen peroxide solution
5) Catalyst for polyhydro-ammonia by substituting silica gel with ball-shaped product
6) Desiccator and purifying agent.
