Activated alumina desiccan


Activated alumina desiccant is a special process made of spherical activated alumina. Its own property is non-toxic, odorless, non-chalky, insoluble in water, white spherical appearance, strong ability to adsorb water. Under certain operating conditions and regeneration conditions, its drying depth up to the dew point temperature below -40 ℃, is a trace of the depth of water and efficient drying agent.

Activated alumina desiccant is mainly used to dry liquids and gases. Widely used in petrochemical gas, liquid-phase drying, for the textile industry, oxygen industry and automation instrument wind drying, air separation industry pressure swing adsorption.
