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 m²/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 a versatile Aluminum Oxide based adsorbent which finds uses in drying of a number of gases and liquids.
Manufactured under stringent quality control and rolled on latest machines, it has high adsorption capacity and crushing strength, which provides low pressure drop in the tower and efficient removal of vapor.

Industrial Applications
· Pressure swing adsorption and other packaged dryers.
· Instrument and low pressure air-drying.
· Scavenging of HF, BF3 from alkylation feed stock.
· Reconditioning of mineral oils like transformer or insulating oils.
· Water defluorination
· Removal of oil vapor mist from compressed air.
· Dehumidification in food and pharmaceutical industries.
· Drying of organic liquids to a moisture level of 10 ppm or below.
· Drying of practically all inorganic gases such as Air, Ammonia, Carbon Dioxide, Chlorine etc. and organics use acetylene, ethane, Ethylene, Freon, etc.
· Drying of various liquids such as Benzene, Carbon, Tetrachloride, Chlorobenzene, Ethyl Acetate, Transformer oil, Vegetable oils etc.
Activated alumina is for use in both heated desiccant air dryers and heatless / pressure swing compressed air dryers. Dew points of -100° F can be achieved depending on dryer design and operating conditions.
3-5 bead alumina is the size most frequently used in regenerative dryers
5-7 bead alumina are used as a pre-bed material to support large desiccant beds and as a pre buffer for silica gel beds in desiccant air dryers.
