Activated Alumina
Activated alumina is a highly porous, ceramic compound that can absorb both gases and liquids without changing form or disintegrating. It is often used to absorb water from the air and fluoride from drinking water. In addition, activated alumina can be regenerated. If heated to approximately 200 , the absorption process is reversed and the aluminas will release the water it has absorbed. Activated alumina is mainly used in gaseous and liquid desiccation in petrochemical industry. It is also widely applied as a dryer in textile industry, oxygen making industry and automatic instrument, equipments with non-heat regeneration.
