ACTIVATED ALUMINA
Activated Alumina
Activated alumina is a specially treated type of alumina (chemical formula Al2O3) with characteristics such as high specific surface area, porosity, high dispersion, and large specific surface area.
Key Features
- ✓BET surface area ≥320 m²/g
- ✓High crush strength ≥80N per sphere
- ✓Low abrasion loss <0.3%
- ✓Available in 3-5mm, 4-6mm and 6-8mm spheres
Activated alumina is mainly used for dehydration of gaseous and liquid in petrochemical ,electronic ,metallurgy industry ,for instance,air ,oxygen ,nitrogen ,ethylene and propylene etc.
