activated alumina has emerged as a vital tower internal in chemical engineering, extensively applied in adsorption, drying, and purification systems. Its operational effectiveness hinges on technical indicators, which dictate packing efficiency, durability, and process stability. Mastery of these indicators is indispensable for optimizing tower internal design and achieving consistent production outcomes.

Core technical indicators of activated alumina packing encompass specific surface area, pore size distribution, bulk density, and thermal resistance. A high specific surface area (typically 200-350 m²/g) significantly boosts adsorption capacity, while well-distributed pores (5-100 Å) facilitate efficient mass transfer. Bulk density, ranging from 0.6 to 0.9 g/cm³, balances packing density and pressure drop, with lower values often ideal for improved fluid flow. Thermal stability, up to 600°C, ensures suitability for high-temperature industrial environments.
These indicators directly influence packing performance. A uniform pore structure minimizes channeling, ensuring even fluid distribution across the tower. High mechanical strength (compressive strength > 8 MPa) prevents attrition, reducing maintenance and replacement needs. Additionally, chemical inertness guarantees compatibility with diverse media, extending service life in corrosive or reactive conditions.
