With a surface area of over 200 m²/g, Activated alumina is  commonly used as a desiccant and a filter of fluoride, arsenic and selenium in  drinking water. It is made of aluminium oxide (alumina; Al2O3) and has a very  high surface-area-to-weight ratio due to its tunnel-like pores.

DESICCANT

 Being  highly adsorbent, water vapour in water and gases stick to the Activated  Alumina and is trapped inside. Handlers can release the trapped water molecules  by heating the desiccant to ~300 °C.
CATALYST

Activated alumina is used for several adsorbent and catalyst  applications such as the adsorption of catalysts in polyethylene and hydrogen  peroxide production. It also acts as a selective adsorbent for chemicals such  as TBC, chloride, COS, and sulphur removal from gas streams (Claus Catalyst  process).
FLUORIDE ADSORBENT
 Activated alumina is also widely used to remove fluoride from  drinking water, easily reducing fluoride levels from 10.0 ppm (parts per  million)  to less than 1.0 ppm.  The amount of fluoride removed from  the water being filtered depends on how long the water actually touches the  alumina filter media. With increased alumina, the amount of fluoride left in  the filtered water decreases. Also, Lowering the temperature and the pH of the  water enables more effective filtering, with 5.5 being the ideal pH, it allows  for up to a 95% removal rate.
CARRIER for CATALYST
 Activated alumina are dried in special  temperature for carrier for catalyst. As carrier, its pore volume is bigger for  support. Our company could help you and do the right catalyst carrier for you.

Regeneration of alumina adsorbent

●In the drying  of activated alumina, regeneration of activated alumina is necessary. The  heating and desorption processes include heating, rinsing and cooling in three  steps. The higher the heating temperature, the more complete the desorption  regeneration. General activated alumina heating regeneration temperature about  350 ℃. The temperature of the  activated alumina tower is generally raised to 280℃ for 4 hours. Heating rate of about 50 ℃ per hour. After the regeneration of the active alumina bed  must be cooled before the adsorption operation, with the cooling gas to wash  the bed, the gas should also be used to try not to contain water, cold gas flow  and adsorption cycle of the same direction. When activated alumina is used for  liquids such as propylene drying, it is necessary to first drive the liquid of  the activated alumina bed at the time of regeneration, without any dead ends.  Otherwise the residual liquid will react or carbonize upon heating, which will  seriously affect the efficiency and operating life of the adsorption cycle.

●If the  activated alumina is good quality, it will improve the life of activated alumina. Certainly, whatever bad or good, you should use desiccant  regeneration for future application. But Good quality activated alumina performance  could improve the life and drying situation. So please purchase activated  alumina from standard activated alumina factory. Trust our company could offer  you the best warranty.
