| NAME | ACTIVATED ALUMINA |
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.
Activated alumina is good of reactivity and stability in use,especially together with our KC-201 will have good effection in sulfur recovery.

Activated alumina is used for a wide range of adsorbent and catalyst applications including the adsorption of catalysts in polyethylene production, in hydrogen peroxide production, as a selective adsorbent for many chemicals including arsenic, fluoride, in sulfur removal from gas streams (Claus Catalyst process).
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.
When exposed to activated alumina,water molecules in the air will bond
to the alumina, thereby resulting in drier air. If the material is
heated, it will release the water bonded to it back into the air, This
process of binding to and releaseing water can be repeated
indefinitely,making this material one of the most common desiccants.
It can also adsorb other materials such as arsenic,fluoride,copper,and
lead,This ability makes it a suitable candidate for use in water
treatment operations. In many cases, it is more cost-effective than a
cutting-edge, large-scale water treatment facility. Activated alumina
water treatment is often the method of choice for rural areas and small
municipal facilities.
