Activated alumina

Epochemmie’s Activated Alumina is X-ρ form active aluminum oxide. It has a strong affinity for water so that it a high efficiency desiccant for micro in water deep desiccation. Its drying (dew point) can be below-70°C under certain operating and regeneration conditions. When applied in a medium, it’s neither become soft nor swell and non-dissolve into powder. So it’s widely used in gas and liquid desiccation in petrochemical industry and used in auto-instrument wind drying of petrochemical, textile and oxygen-making industries, PSA in air-separation etc. Due to high heat-adsorption quantity of single molecular adsorbing layer, so it is very suitable for the use of heat-free regeneration device.

Epochemmie offers various grades of Activated Alumina for many usage areas
