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.
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.
