Features

High Adsorption Capacity: Activated alumina balls have a large surface area (up to 415 m²/g), which allows them to effectively adsorb moisture and other impurities from gases and liquids.
Thermal Stability: They are resistant to thermal shock and can withstand high temperatures without degrading.
Mechanical Strength: These balls have high crush strength, which prevents them from breaking down during use, ensuring long-term performance.
Chemical Inertness: They are non-toxic, non-flammable, and non-reactive, making them safe for use in a variety of applications.
No Swelling or Shrinking: When immersed in water, activated alumina balls do not swell, shrink, or soften, maintaining their structural integrity.

Application

Air Drying: Used in air drying systems to remove moisture, providing dry air with dew points as low as -47°C to -50°C.
Gas Drying: Effective in drying various gases such as LPG, propylene, aromatic solvents, and gasoline.
Water Treatment: Used to remove fluoride and other impurities from drinking water, making it suitable for defluorination treatment in high-fluorine areas.
Catalyst Support: Serve as catalyst supports in the production of hydrogen peroxide and the purification of hydrocarbons.
Pollutant Removal: Can absorb pollutants such as H2S, SO2, HF, and water vapor from industrial gases and wastewaters
