4. Activated Alumina / Hydraulic Alumina
Activated Alumina : Powder Shape

Activated Alumina can be used as an adsorption refining
agent, especially to refine non-polar solvents.
In general, the more polarity and heavier molecularweight, the better adsorption effect would be obtained.
Adsorption order example as follows.
-SO3H > -COOH > -OH, -NH2, -SH > -CHO
> -CO > -COOR > -S-, -O- > -X
> Unsaturated hydrocarbons> Saturated hydrocarbons
Adsorption performance can be measured in terms ofadsorption rate and transmission rate of the picric acidby sending a benzene solution of picric acid through acolumn filled with activated alumina.

KHD-24(Actual)

Hydraulic Alumina
An alumina powder with a large surface areaand some crystal water.
Used as a binder for refractories instead ofalumina cement due to large caking capacityand plasticity.

Condition/setting time of the hydraulic alumina and water mixture* Setting time is determined by JIS R 5210 needle penetration method (slurry thickness 38mm).
Distance between the slurry bottom and the needle is 25mm.
