Spherical Activated Alumina Support / Carrier for Adsorption (γ-Al2O3)
High-purity spherical alumina support engineered as a robust catalyst carrier and specialty adsorbent matrix. Tailored pore structure, exceptional crushing strength, and high hydrothermal stability.
BET Surface Area: 280 - 360 m²/g Pore Volume: 0.38 - 0.50 cm³/g Sizes: 1-2mm, 2-3mm, 3-5mm, 4-6mm,5-8mm
Uniform spherical alumina beads with customizable pore distribution for efficient active component loading.
Key Performance Features as Support Media
- Optimized Pore Structure: High surface area paired with tailored macro/meso pore volume, ensuring rapid mass transfer and uniform active metal impregnation.
- High Mechanical Crush Strength: Superior physical durability prevents bed compaction and channeling under high pressure swings or heavy liquid loads.
- Chemical & Hydrothermal Inertness: Maintains structural integrity during continuous high-temperature regeneration and exposure to harsh acidic/basic environments.
- Low Attrition & Dust-Free: Smooth spherical surface eliminates dust creation, protecting downstream process equipment and pumps.
