Activated Alumina
Desiccant
Use as a desiccant, it works by a process called adsorption.
1) The water in the air actually sticks to the alumina itself in between the tiny passages,
as the air passes through them.
2) The water molecules become trapped so that the air is dried out as
it passes through the filter.
3) This process is reversible, and if the alumina desiccant is heated to about
200°C it will release all of the water stored in it.
4) This process is called regenerating the desiccant.
5) Air always has some water in it; one way to measure the amount of
water in the air is the air's .
Applications:
1, dehydration for air, natural gas, cracked gas oil.
2, fluoride removal for drinking water
3, catalyst and absorbent for hydrogen peroxide solution by anthraquinone process.
4, viscous resin dechlorination
5, catalyst vector
