Activated alumina desiccant is a spherical activated alumina made by special process. Its own properties are non-toxic, odorless, non-pulverizing, insoluble in water, white spherical in appearance and strong in water adsorption. Under certain operating conditions and regeneration conditions, its drying depth is as high as the dew point temperature below -70℃, which is manly used for drying of liquids and gases.
Activated alumina is a highly efficient desiccant with deep absorption of trace water, has advantages of uniform size, high strength, low abrasion, strong water absorption ability, stable performance of regeneration and recycling. In certain situations, the dew point of drying depth can be less than or equal to -70℃. This product mainly used in the drying of gas-liquid products in petrochem-ical industry. Due to the high net heat of single molecule adsorption layer, it is very suitable for the device without heat regeneration.
