Activated alumina ceramic balls are a porous, highly dispersed solid material, primarily composed of transitional alumina phases (such as γ-Al2O3). They are produced through specific thermal activation processes using industrial aluminum hydroxide or aluminum salts as raw materials. Their internal structure features a developed pore network, resulting in a high specific surface area, while their surface properties exhibit high reactivity and excellent adsorption capacity. Typical physical characteristics include a porosity of approximately 45%-55%, a specific surface area usually between 200-360 m²/g, and a bulk density ranging from 0.68 to 0.85 g/cm³. They possess high mechanical strength, good abrasion resistance, and strong chemical stability, maintaining structural integrity under various pH conditions and at elevated temperatures.
This material finds extensive application in fields such as petrochemicals, chemical engineering, gas separation and purification, environmental protection, and healthcare. Its primary functions include serving as an adsorbent for deep drying of gases and liquids, achieving dew points below -70°C; acting as a catalyst support in reactions like hydrogenation, dehydrogenation, and hydrocarbon reforming; removing fluoride and arsenic from drinking water and industrial wastewater; and functioning as a medium for chromatographic separation. In Pressure Swing Adsorption (PSA) units, it is a crucial packing material for the selective adsorption and separation of gases. Its performance stability and reliability have been proven through long-term industrial practice.
The key technical parameters of the product directly influence its application efficiency. Besides specific surface area and porosity, adsorption capacity (e.g., water adsorption capacity, typically >17%), crushing strength (single ball, usually >100N), attrition loss (typically <0.3%), and various particle size specifications (common sizes include 1-3mm, 3-5mm, 4-6mm, 5-7mm, 6-8mm) are core selection criteria. Users must select the appropriate type based on specific process conditions, such as operating temperature, pressure, fluid composition, and regeneration frequency, to achieve optimal techno-economic performance. Strict quality control ensures highly consistent and reproducible properties.
