Activited Alumina for Deoxidation of sulfur recovery cytalyst
Activated Alumina is a song formof Aluminium Oxide that is very porous and
bonds with certain liquid and gases without its chemical or physical
form changing, Due to its high porosity, it has a high ratio of surface
area to weight, it is commonly used as a desiccant, for water
treatment song, and as a catalyst in NAtural gas and refining operations.
A desiccant is a substance with a high affinity for water,which has a
drying effect on its local atmosphere,such as inside a sealed
container,As a desiccant, Acticated Alumina operates by the process of
adsorption, thi should not be confused with the more commonly know
process of absorption, Absorption is a physical process by which a
fluids is drawn into and fills the empty spaces In a solid without
bonding to it.
Adsorption, on the other hand,is a process in which the
fluid drawn into the solid material's pores actually bonds chemically
with of the solid material.
Activated of alumina is manufactured from aluminium hydroxide by
dehydroxylating it in a way that produces a highly porous material;
this material can have a surface area significantly over 200 square
metres/g.
The compound is used as a desiccant (to keep things dry by
absorbing water from the air) and as a filter of fluoride, arsenic and
selenium in drinking water.
It is made of aluminium oxide (alumina;
Al2O3 song), the same chemical substance as Sapphire and Ruby (but without
the impurities that give those gems their color).
It has a very high
surface-area-to-weight ratio, due to the many "tunnel like" pores that
it has.
