Regeneration of activated alumina
●In the drying cycle, regeneration of active 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 heating regeneration temperature is about 350 ℃. The temperature of the 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 alumina bead is used for liquids such as propylene drying, it is necessary to first drive the liquid of the 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 active aluminium oxide has good quality, it will improve its life. Certainly, whatever bad or good, you should use desiccant regeneration for future application. But Good quality performance could improve the life and drying situation. So please purchase aluminium oxide from standard activated alumina factory. Trust our company could offer you the best warranty.

FAQ：
Q: Do you have professional team for our special active alumina to satisfy our data requirement?
A: Our engineer and technical team includes 8 people to research and develop activated alumina. Until now, we don't confront any trouble on the data.
Q: How long is the service life?
A: Usually, it is at least 2 years or 8000 hours. As our experience, 5 years is no issue for ours.
Q: How to store alumina?
A: Firstly, Avoid moisture, avoid scrolling, throw and sharp shocking during transportation, rainproof facilities should be readied. Then it should be stored in dry and ventilated warehouse to prevent contamination or moisture.
Q: Can active aluminium oxide be regenerated?
A: Yes, it could be regenerated with right method. You could contact us for more information.
