Activated alumina is a type of alumina with a high specific surface area, porous alumina. It can adsorb gases and liquids, and it acts as a desiccant through adsorption. When air passes through the alumina, the water in the air sticks to it and is trapped, and the air passing through the activated alumina filter dries out. Even when immersed in liquid, activated alumina does not spread out or soften. Heating activated alumina to any temperature of 350° to 600°F (177° to 316°C) can restore the original adsorption efficiency of activated alumina. When the desiccant is heated as described above, the water stored in it is released. This means that filters containing activated alumina can be used over and over again.
Available types of activated alumina: Activated alumina has a variety of uses such as desiccant, catalyst carrier, sulfur recovery, etc. After adding different additives, activated alumina is used for catalysts and purification, such as dechlorinator, polyethylene purification, etc
