Activited Alumina for Deoxidation sulfur recovery cytalyst
Activated Alumina is a form of 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, 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 the solid material.
Activated 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), 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.
