Product Description

Activated Alumina: Key Characteristics & Applications

Activated alumina  is a highly versatile material with several industrial applications due to its unique properties. 

1. Definition and Properties
Activated alumina is a porous, high-surface-area form of aluminum oxide (Al₂O₃).
Key characteristics:Adsorption capacity: Effective for removing water and other polar compounds.
Thermal stability: Maintains structure at high temperatures (up to ~500°C).
Mechanical strength: Resists crushing, especially in spherical forms.
2. Applications
Catalysis: Widely used as a catalyst or catalyst support in petroleum refining, chemical synthesis, and pollution control (e.g., sulfur removal) .
Drying agent: Deep desiccant for gases and liquids (e.g., in compressed air systems).
Adsorption: Removes impurities like fluoride (in water treatment) and oil vapors (in industrial processes).
3. Forms and Features
Spherical activated alumina: Preferred for pressure swing adsorption (PSA) due to uniform size, smooth surface, and high crush resistance.
Non-toxicity: Safe for use in food-grade and pharmaceutical applications.
