Activated Alumina, Desiccant, Drier, absorbent

Activated Alumina
1.no smell, odorless
2.insoluble to water and organic solvents
3.size:1.2-2.4,3-5,1-3,5-8mm
Activated alumina
has 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-molecular absorbent, according to the absorbed molecular polarization, the attachment force is strong for water, oxide, acetic acid, alkali etc.

The
big diffrernce

between activarted alumina and the anion exchange resin is the selectivity.The selectivity of activated alumina is much stronger,and its defluorination is good.

The capacity is stable, the absorbed fluorine is 6400g/cm3. It has high strength, low abrasion, no soften in water, no expansion, no powdery, no crack.

At the same time,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 water gas, especially in the drinking water defluorination
