The specification of large pore volume activated alumina:
Large pore volume activated alumina
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.
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.
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).
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.
