1-12mm active alumina particles can be customized activated alumina ball alumina having adsorption properties, the catalytic activity of the porous, high dispersion, large specific surface area. Activated alumina ball inside the main crystal composition according to type into γ and χ-ρ type, their use can be divided into active alumina ball adsorbent, activated alumina and activated alumina desiccant ball ball catalyst carrier. ASU --- desiccant activated alumina ball (Activated Alumina) due to the net heat of single molecules adsorbed layer is high, so is ideal for non-thermal regeneration unit. Product appearance is white, spherical porous material, non-toxic, odorless, not powder, insoluble in water, ethanol. Having a plurality of capillary channels, a large surface area, can be used as an adsorbent, desiccant, catalyst carriers. High strength, low wear, flooding the same soft, not inflated, not powder, not rupture characteristics.

For gas regeneration operation should be: ① has a job or is lower than the same pressure when dry, dry gas; ② have higher than or the same as the temperature of the drying operation of dry gas; ③ warmed wet gas; ④ decompression After the wet gas.
