ACTIVATED ALUMINAS
AA Series
UOP Activated Aluminas*

UOP Activated Alumina adsorbents are used in the drying and purification of gases and liquids in a wide range of industries. Because of the affinity of the alumina surface for water that provides the driving force for drying, UOP has developed products with optimal surface area and pore size distribution. UOP Activated Alumina spheres are "activated" by a proprietary process to achieve specific surface chemistry and reactivity.

Type A-201 Activated Alumina

Type A-201 is a spherical activated alumina that has high surface area, adsorption capacity and abrasion resistance. Activated Alumina Type A-201 is used as a desiccant or drying agent, for industrial liquids and gases, such as air, nitrogen, oxygen, carbon dioxide and hydrocarbons. It is recommended for all dehydration units using thermal regeneration.

Type D-201 Activated Alumina

Type D-201 is a spherical activated alumina with high surface area, high adsorption capacity and excellent abrasion resistance. Activated Alumina Type D-201 is an abrasion resistant desiccant that has excellent adsorption and desorption characteristics. It is recommended for use in dehydration systems where the desiccant is subject to harsh mechanical conditions, and is especially suitable for heatless (pressure swing) air dryers.
