Activated Alumina Microspheres Adsorbent

Activated Alumina Microspheres Adsorbent is a porous adsorbent material prepared from high-purity alumina raw materials through processes such as pelletizing, aging, activation, and high-temperature calcination. This product features a large specific surface area, high pore volume, uniform pore size distribution, high mechanical strength, low wear, and strong adsorption capacity, making it widely applicable in air drying, gas drying, water treatment, catalyst support, hydrogen peroxide production, and gas purification in the petrochemical industry.

Compared to ordinary activated alumina balls, activated alumina microspheres have smaller particle sizes, larger specific surface areas, faster adsorption rates, and higher contact efficiency, making them particularly suitable for PSA units, precision drying equipment, deep dehydration, and high-efficiency adsorption systems.
