Activated Alumina product is manufactured by dehydroxylating where it produces highly porous materials from aluminum hydroxide. ... Water molecules are being trapped between the small passages of the alumina itself, which enables it to dry as it goes through the filter. Activated Alumina is also used in vacuum application.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 fluid streams.

Application:

CATALYST Grade


Activated alumina is also used as a catalyst, with roles as the catalyst itself, as well as an inert carrier, or substrate for other catalysts.Activated alumina catalyst can be widely used in the deep drying of petroleum cracking gas, ethylene propylene gas, hydrogen production, air separation plant, instrument air drying machine, fluoride treatment in hydrogen peroxide.

. DESICCANT Grade



Similar to its role as an adsorbent, activated alumina can also adsorb water from air, allowing it to be used as a desiccant; activated alumina can capture and trap water in order to keep things dry, much like silica gel. As a desiccant, activated alumina can adsorb up to 20% of its own weight in water at a relative humidity of 50%.1

Activated alumina is employed as a desiccant in a wide variety of applications, including the removal of water vapor from gases in industrial settings. Water adsorbed onto the activated alumina can then be desorbed via thermal treatment and the alumina reused.And it is a high-surface-area, highly porous form of aluminum oxide. It can adsorb gases and liquids without changing its form. It works as a desiccant through adsorption. As air passes through the alumina, the water in the air sticks it and becomes trapped and air that passes through an activated alumina filter is dried out.  Even if immersed in a liquid,AA won't fall apart or soften.


ADSORBENT Grade


Activated alumina is a highly effective adsorbent in both gas and liquid applications, and as such, is employed by a number of industries for targeted removal of components from other media.

As an adsorbent, activated alumina is most well known for its use in water filtration applications, where it serves as a cost-effective adsorbent for removing fluoride from water. It is also capable of removing a variety of other contaminants, including arsenic, lead, and sulfur.Activated alumina fluoride agent is a kind of adsorption material, high specific surface area and high entrance are the basic characteristics of adsorption material, the effect of activated alumina has certain adsorption impurities, in fact, activated alumina (100 ~ 500 a) can be divided into big hole, the hole (40 ~ 100 a), microporous (< 40 a) and pore size distribution range from 10 a ~ 500 a, activated alumina for less than its aperture of molecules, has certain adsorption ability.
