Activated alumina is an invaluable desiccant, protecting products from moisture damage with its expansive surface area and crystal lattice structure that absorbs significant quantities of airborne and liquid impurities.
Eco-friendly low-heat solid-phase methods of production enable it to be manufactured. Its properties depend heavily on both its original bauxite source as well as the thermal processing and agglomeration method employed.
Activated alumina has a crystalline lattice structure
Active Alumina (AA) features an open crystalline lattice structure composed of pores and voids which allow it to absorb gases, liquids and dissolved species from its environment. Due to its high porosity, AA can adsorb large volumes of materials; its high porosity also enables it to be formed into different shapes such as beads, pellets, granules or powders; its bulk density varies based on manufacturing methods and applications for which it was designed.
Activated alumina is an effective desiccant for extracting moisture from industrial processes and compressed air systems, protecting product quality and stability while countering corrosion caused by humidity. Furthermore, activated alumina’s powerful absorption capacity helps prevent corrosion damage caused by humidity as well as prevent the formation of harmful hydrates that obstruct pipelines.
These characteristics make activated alumina an invaluable material in multiple applications, from water treatment to waste management. Furthermore, activated alumina’s unique porous structure provides a large specific surface area which makes it an invaluable catalyst carrier in many adsorption reactions.
When handling activated alumina, be sure to use PPE, such as safety goggles and gloves, when working with this material. Ingestion or inhalation of its dust can cause irritation or respiratory problems; furthermore it’s essential that spill management procedures be strictly adhered to – spills must be immediately contained and cleaned up after occurring, not being stirred to disperse particles further into the atmosphere.
It has a high surface area-to-volume ratio
Activated alumina boasts superior adsorption properties, making it an invaluable component in many industrial processes. It has an expansive surface-to-volume ratio which enables it to quickly absorb gases and liquids. As such, activated alumina has wide application in water treatment, gas purification, desiccant use and desiccant applications; many uses for desiccant usage include water treatment, gas purification and desiccant desiccant uses as well. Activated alumina has affinity with various chemicals and gasses including hydrogen, argon chlorine SO2, SO3 as well as NH3. Furthermore it can even be used for drying kerosene aromatic compounds and essences
Adsorption capacity of activated alumina depends on factors like its pore size, particle size and adsorption temperature; its rate also varies with flow rate and contamination concentration; for this reason it is important to understand its adsorption process before employing this material.
For optimal adsorption capacity, activated alumina must have its pore structure properly prepared. This can be accomplished through controlled heating of hydrated alumina which causes water molecules to escape along planes of structural weakness, producing a porous material with well-defined pores and networks.
Adsorption rates range from 100 to 300 m2/g, making activated alumina an excellent choice for industrial uses where quick adsorption times are essential. Furthermore, activated alumina has superior attrition resistance compared to silica gel and retains more of its adsorption capacity at higher temperatures than either product.
It has a high crush strength
Activated alumina is an adsorbent that can selectively adsorb molecules, enabling it to remove impurities from gaseous and liquid media. It is used in many applications including air separation, natural gas refining, petrochemicals, industrial drying, air purification systems and drying applications. Due to its ability to target specific compounds it is especially helpful when used for industrial processes that require high purity levels.
Activated alumina stands out from silica gel by having an exceptionally high crush strength, enabling it to be crushed and sieved into granules of any desired size for various applications. Additionally, this allows bulk handling more easily – an important aspect in many situations where handling large volumes is key. Particle size impacts surface area and pore structure which ultimately determines moisture absorption properties of materials such as activated alumina.
When working with activated alumina, it is vitally important to use appropriate personal protective equipment (PPE). This may include safety goggles or face shields, chemical-resistant gloves and a dust mask or respirator. Storage conditions must also be optimal to ensure optimal activated alumina performance in processes. Testing compatibility is therefore key in order to develop activated alumina products which deliver on expectations in any process environment. FEECO Innovation Center provides an innovative testing environment, combining thermal processing and agglomeration tests in one setting for seamless data collection and simulation of production conditions that will lead to an agglomerate with the desired characteristics.
It has excellent adsorption properties
Activated alumina is an innovative material with excellent adsorption properties for extracting impurities and moisture from various environments, making it the ideal material to control moisture in applications ranging from petrochemical production processes to gas production operations. Moisture control is crucial to product quality assurance while mitigating downtime due to equipment breakdown – activated alumina desiccants are an economical means of meeting this objective.
Activated alumina’s bulk density depends on its manufacturing process and intended application; typically ranging from 0.6 to 0.8 grams per cubic centimetre. Its white hue helps identify it as powder or dust for easier identification in most environments; it should not be considered toxic; however it is wise to wear PPE such as chemical-resistant gloves and face mask when handling this material.
Alumina differs from stable crystalline forms in that its large surface areas allow it to adsorb large molecules with low water binding energy, making it the ideal material for phosphate, fluoride and arsenic removal. Furthermore, FEECO Innovation Center boasts thermal and agglomeration testing capabilities which enable scientists to tailor custom formulations specifically tailored to different applications.
