Activated alumina powder features well-developed mesoporous (pore diameters ranging from 2 to 50nm) and macroporous (>50nm) structures, with a specific surface area of up to 200 to 400 m²/g and a pore volume of 0.3 to 0.8 cm³/g, demonstrating strong adsorption capacity.
Activated alumina have a large number of hydroxyl groups (-OH) on the surface, which can undergo physical or chemical adsorption with molecules in water, gas or solution, and it has certain acidity or alkalinity. Activated alumina Powder products can be formed into spherical, columnar and other particles after molding (such as granulation, extrusion), which have certain compressive strength and are suitable for filled beds or catalyst carriers.
Application of Activated Alumina
Desiccant:
As a powerful desiccant, activated alumina is widely used to remove moisture from gases and liquids in industries like petrochemicals, pharmaceuticals, and air conditioning systems. The high surface area and porosity of activated alumina make it highly effective in capturing and retaining water molecules, preventing moisture-related issues such as corrosion and product degradation.
Adsorbent:
Activated alumina serves as an effective adsorbent for the removal of various contaminants from air, water, and industrial processes. Some common contaminants removed by activated alumina include fluoride, arsenic, sulfates, and various organic compounds.
Catalyst support:
Owing to its high surface area and thermal stability, activated alumina is often used as a catalyst support in the chemical industry. The porous structure of activated alumina allows for the even distribution of active catalyst components, ensuring optimal catalytic activity and prolonging the life of the catalyst.
Other applications:
Besides its primary uses, activated alumina has found its way into various other applications such as chromatography, abrasive products, and as a filler material in the manufacturing of plastics and ceramics.
Production Process of Activated Alumina
Production of aluminium hydroxide: Throughout most instances, activated alumina begins as aluminum hydroxide (gibbsite, boehmite, etc.) — a substance formed by a sequence of chemical reactions during the bayer procedure, which converts bauxite ore to alumina.
Activate alumina calcination: The aluminium hydroxide is then thermally processed in a rotary kiln once it has been created. This calcination stage is applied to dehydration or removing bound moisture from aluminium hydroxide, in order to form alumina or aluminium oxide.
Activated alumina agglomeration: Agglomeration is typically desired based on the activated alumina’s desired final application. When dealing with adsorbents and catalysts, this is particularly true.
Activated alumina testing: Testing is typically a vital step in the development of an activated alumina output that works as expected for a variety of purposes. Batch and pilot-scale kilns are frequently used to test the thermal procedural components of activated alumina manufacturing.
