Everyone knows that active aluminum oxide has certain regeneration capabilities. Therefore, when we use it, we generally utilize its regeneration functions to complete relevant operations and ensure strict implementation. The appropriate regeneration temperature is indeed beneficial for its use. Hence, it is necessary for users to understand the regeneration temperature of the aluminum oxide. Below, we will specifically introduce how its regeneration temperature is determined.
Desorption heating temperature should be maintained between 120-180°C, while the blue indicator, color-changing desiccant, and DL blue active alumina desiccant should be kept between 100-120°C.
2. The maximum temperature during the regeneration of various industrial desiccants must not exceed the following limits:
(1) The coarse pore regenerant cannot exceed 600°C.
(2) Pores should not exceed 200°C.
The blue adhesive indicator (or color change) must not exceed 120°C.
3. For the blue adhesive indicator or the变色active alumina regenerant, the desorption regeneration temperature must not exceed 120°C; otherwise, the colorant will gradually oxidize and lose its coloration effect.
During the drying and regeneration process, it is important to gradually increase the temperature to avoid sudden drying that could cause granules to crack, thereby reducing the recovery rate.
During the regeneration process, excessive temperatures can lead to changes in pore structure, significantly reducing adsorption efficiency and impacting usability.
After regeneration, the particles should be screened to remove them, ensuring uniformity.
This overview mainly covers knowledge about the regeneration temperature of activated alumina. This product inherently possesses regeneration capabilities. To achieve the regeneration function, it is essential to meticulously control the temperature at the appropriate regeneration level.
