Activated aluminais Overview
Activated aluminais manufactured from aluminium hydroxide by dehydroxylating it in a way that produces a highly porous material,this material can have a surface area significantly over 200 m²/g. The compound is used as a desiccant (to keep things dry by absorbing water from the air) and as a filter of fluoride, arsenic and selenium in drinking water,also it can be used as SRU catalyst or catalyst support material.
Activated alumina is made of aluminium oxide (alumina; Al2O3) which is a high-surface-area, highly porous form of aluminum oxide. It can adsorb gases and liquids without changing its form. It works as a desiccant through adsorption. As air passes through the alumina, the water in the air sticks it and becomes trapped and air that passes through an activated alumina filter is dried out.Even if immersed in a liquid,activated alumina will not fall apart or soften.
You can restore the original adsorption efficiency of activated alumina by heating it to any temperature from 350° to 600°F (177° to 316°C). When the desiccant is heated as described above, the water stored in it is released. This means that filters with AA can be reused over and over again.
CHEMPACK produces a variety of standard and customized activated aluminas for adsorption and catalytic applications in oil refining, petrochemical, gas processing and related industries.
Production of Activated Alumina
In most cases, activated alumina starts out as an aluminum hydroxide (gibbsite, boehmite, etc.) – a material obtained through a series of chemical reactions in the Bayer process used to transform bauxite ore into alumina.
Activated Alumina Calcination
Once the aluminum hydroxide has been produced, it is thermally treated via calcination in a rotary kiln. This calcination step serves to dehydrate, or remove bound moisture from the aluminum hydroxide in order to produce alumina, or aluminum oxide (Al2O3).
Activation, a phase in which the alumina structure becomes highly porous, occurs within a specific temperature range, with process parameters such as residence time and temperature profile used to control the properties of the end product. The makeup of the original bauxite source can also influence the characteristics of the end product.
Activated Alumina Agglomeration
Depending on the intended end use of the activated alumina, agglomeration is also often desirable. This is especially true when working with adsorbents and catalysts.
The agglomeration of activated alumina allows for a high level of customization for specific application requirements. Characteristics that are often controlled through agglomeration include:
Particle size distribution,Bulk density,Crush strength,Amount of attrition/potential for dust generation,Flowability,And more…
There are many ways to produce activated alumina “beads,” as they are often called, with some options including the use of an agglomerator, pin mixer, disc pelletizer, or combination thereof.
Activated Alumina Testing
For many reasons, testing is often a critical step in the success of an activated alumina product that performs as desired. It is often necessary to test the thermal processing aspects of activated alumina production using batch- and pilot-scale kilns. Additionally, it is often recommended to test the various methods of agglomeration, as well as potential binders in order to gather the process data necessary to produce an agglomerate with the required characteristics.
The CHEMPACK Innovation Center is a testing facility where both thermal and agglomeration testing can be carried out at batch and pilot scale. Continuous process loop testing integrating thermal and agglomeration can also be tested. This unique testing environment allows process and material data to be gathered, and production conditions to be simulated in order to create a process that will produce a product suited for the intended application.
Activated Alumina Applications
Much like activated carbon, the high surface area and porosity exhibited by activated alumina allows it to capture and hold on to various types of materials, lending it to be employed as an adsorbent, desiccant, and more. The primary ways in which activated alumina products are used include:
Conclusion
Due to its capabilities as an adsorbent, desiccant, and catalyst, activated alumina is a valuable tool in many industrial process settings. Produced from the activation of aluminum oxide resulting from the Bayer process via calcination, activated alumina is highly customizable and is often agglomerated to improve performance and handling characteristics. Feasibility testing is often a useful endeavor when working with activated alumina products.
CHEMPACK offers comprehensive testing capabilities for both the thermal treatment and agglomeration of activated alumina, as well as alumina and bauxite.
