Activated Alumina Ball


Activated alumina has much micro-paths, so the specific surface is large. It can be used as absorbent desiccant and catalyst carrier. It is also a kind of trace water desiccant and the pole-molecular absorbent, according to the absorbed molecular polarization, the attachment force is strong for water, oxide, acetic acid, alkali etc..

Activated alumina defluorinated just as the anion exchange resin, but the selectivity is much strong. The defluorination effect of the actived alumina is good. The capacity is stable, the absorbed fluorine is 6400g/cm3. It has high strength, low abrasion, no soften in water, no expansion, no powdery, no crack.

It can widely used in the deep drying of cracked gas, ethylene and propylene, hydrogen-generation, air separation, instrument air drying and fluorine treatment for H2O2, also in the absorbing pollution material, such as H2S, SO2, HF and paraffin in the water gas, especially in the drinking water defluorination.

Molecular Formula:  Al2O3•n H2O(0<N≤0.8)

Physical Properties

Activated Alumina Ball – High-Performance Adsorbent & Desiccant

Activated Alumina Balls are highly porous, spherical adsorbents made from aluminum oxide (Al₂O₃). Due to their large surface area, high adsorption capacity, and excellent thermal stability, they are widely used for drying, purification, and separation processes in various industries.

Key Features & Advantages:

  • High Adsorption Capacity

    • Effectively removes moisture, impurities, and contaminants from gases and liquids.

  • Excellent Thermal Stability

    • Withstands high temperatures without losing adsorption efficiency.

  • Regenerable & Reusable

    • Can be regenerated through thermal heating for long-term use.

  • High Mechanical Strength & Low Dust Formation

    • Ensures durability and prevents breakage during operation.

  • Non-Toxic & Environmentally Safe

    • Chemically inert and stable, making it safe for industrial and food-grade applications.

Applications of Activated Alumina Balls:

  1. Air & Gas Drying

    • Used in compressed air dryers, natural gas dehydration, and industrial gas drying.

  2. Water Purification & Fluoride Removal

    • Removes fluoride, arsenic, and other contaminants from drinking water.

  3. Catalyst Carrier & Support

    • Serves as a substrate for catalysts in petrochemical and refining processes.

  4. Hydrogen Peroxide Production

    • Used in purification and stabilization of hydrogen peroxide.

  5. Desiccant for Chemical & Pharmaceutical Industries

    • Protects moisture-sensitive products by maintaining a dry environment.
