Activated alumina is a kind of highly efficient desiccant for micro-water. Its drying depth can reach dew point temperature – 70 C, and static water adsorption can reach more than 17%. Common specifications are 1-3, 2-4, 3-5, 4-6, 5-7 mm, which are widely used in air separation, pressure swing adsorption, petrochemical industry and gas drying of automatic instruments。
