Product Description Activated AluminaActivated Alumina (chemical formula Al2O3) is a porous, high-surface-area adsorption material made from aluminum hydroxide or aluminum salts activated by high-temperature calcination. Due to its excellent physical and chemical properties, such as high adsorption capacity, thermal stability and renewability, it is widely used in gas and liquid drying, catalysis, water treatment and environmental protection. Compared with traditional desiccants such as silica gel and molecular sieves, activated alumina is more stable in high temperature, high humidity and corrosive environments, and is one of the key materials in industrial adsorption and catalysis processes. ApplicationGas drying:Deep dehydration of industrial gases such as compressed air, natural gas, and hydrogen (dew point can be reduced to below -70oC).Drying of refrigerants such as Freon in refrigeration systems to prevent "ice blockage".Liquid drying:Dehydration and deacidification of organic solvents (ethanol, benzene) and oil products (lubricating oil, transformer oil).Environmental protection and purificationWater treatment: Adsorption of harmful ions such as fluoride, arsenic, and lead in wastewater (especially in drinking water purification).Waste gas treatment: Removal of pollutants such as SO2, H2S, and VOCs.Catalysts and carriersAs catalyst carriers, used in petrochemicals (such as hydrogenation and desulfurization reactions) and automobile exhaust purification (loading precious metals).Special usesLaboratory: Desiccant in drying towers and moisture-proof cabinets.Medical: Gas drying of medical oxygen or ventilators Product Parameters PropertyParameter Range/ValueRemarksChemical CompositionAl2O3 ≥ 92-95%Impurities include Na2O, SiO2, etc.Crystal StructurePrimarily γ-Al2O3 May contain trace α-Al2O3 Surface Area (BET)200-400 m2/gMeasured by BET methodPore Volume0.3-0.6 cm3/gMainly mesopores (2-10 nm)Average Pore Size3-8 nmAdjustableBulk Density0.6-0.9 g/cm3Depends on particle formCrush Strength≥50 N/bead (3-5 mm spheres)Industrial-grade requirementWater Adsorption Capacity15-20% (25°C, 60% RH)Humidity-dependentRegeneration Temperature200-350°CUnder inert gas or vacuumTemperature ResistanceShort-term: 600°C, Long-term: ≤400°CHigh temps may convert to α-Al2O3 pH StabilityStable at pH 4-10Dissolves in strong acids/alkalisDew Point After Adsorption≤-70°C (deep drying)For compressed air, etc.Attrition Rate≤0.5% (spherical particles)Affects service life Detailed PhotosActivated alumina has a highly porous structure (specific surface area 200-400 m2/g) and abundant surface hydroxyl groups (-OH), which can capture water molecules in gas or liquid by physical adsorption. Its polar surface forms hydrogen bonds with H2O to achieve deep drying (dew point ≤-70oC). When regenerated at high temperature (200-350oC), the adsorbed water molecules are desorbed and the drying capacity is restored.Activated alumina selectively adsorbs polar molecules (such as SO2, VOCs) through its mesoporous structure (2-10 nm) and surface charge. The Lewis acid sites (Al3+) in its γ-Al2O3 lattice can chemically adsorb compounds containing lone pair electrons (such as sulfides), while physical pores intercept molecules.Regeneration of activated alumina relies on thermal desorption: when heated to 200-350°C, the kinetic energy of adsorbed water or pollutant molecules increases and they detach from the surface. Chemical adsorbates (such as F-) require acid/base cleaning (such as NaOH solution) to restore activity. After regeneration, the performance decreases by ≤20%.Related productsporcelain ceramic ball Ceramic Ball alumina ceramic ball ceramic ball mill Support Catalyst Ceramic Packing Grinding Ball High Alumina Ceramic Ball ceramic alumina ball alumina grinding ball grinding ball price grinding ball mill grinding ball mill balls alumina ball price porcelain ceramic ball alumina ceramic ball ceramic ball millProduct LinePackaging & ShippingFAQQ1: Where Is Your Factory Located?A: Our factory are located in No.1-269, Zone B, Xiangdong Industrial Park, Xiangdong District, Pingxiang City, Jiangxi,China.welocme your visiting.Q 2: What Are Your Main Products?A:Our factory mainly produces various kinds of ceramic balls (including Activated alumina, Grinding Ball, Refactory Ceramic Ball, Porous ceramic ball,Zirconia Ball, Ceramic Inert Ball etc. ),molecular sieves(including 3A/4A/5A/13X etc.) ,actived alumina, tower random packing(including plastic/metal/ceramic material of Pall Ring,intalox saddle lMTP,Raschig Ring,Cascade Mini Ring etc.), structured packing(including Vane demister, Plastic Mesh Demister, Wire Mesh Separator Demister,Ceramic/plastic/metal Structured Packing etc.),Honeycomb ceramic,Ceramic Bio Bacteria Ball,Ceramic Acid Proof Brick,Exteriment packing etc.Q3: What Kind Of Payment Do You Accept?A:we accept T/T,western union.Q4:What's your terms of delivery?A:EXW, FOB, CIF .Q5: Can I get free samples?
