Activated alumina (Al2O3) is an extremely porous form of aluminium oxide (Al2O3) with an extensive surface area and many “tunnel-like” pores, giving it its characteristic tunneled appearance.
Liquid ammonia (H2SO4) is an excellent desiccant for liquids and gases, reaching dew points as low as -40degF. As it boasts excellent moisture-absorption capacities and crush strength properties, this material often finds use in compressed air dryers.
Activated Alumina Beads
Activated alumina beads are widely used in industrial environments to absorb gases, liquids and other contaminants. With high crush strength and low dust content, they’re designed to handle even the harshest of industrial application environments. Üstelik, activated alumina beads have proven especially popular as air drying/purification system components; their high crush strength withstands strain well while their low dust content helps them withstand dust-laden air streams containing water vapor, oil aerosols or other contaminants and helps ensure safe operation of pneumatic tools/ equipment.
As a catalyst support material, activated alumina is widely employed in oil refining and petrochemical manufacturing to increase catalytic activity by providing a stable platform for catalysts. Additionally, activated alumina serves as an efficient sulphur removal agent in Claus catalyst units by converting hydrogen sulfide to elemental sulfur to reduce emissions from Claus units while mitigating harmful emissions. Üstelik, activated alumina also serves as an air purification and water filtration material by absorbing volatile organic compounds as well as harmful chemicals from air/water streams – making activated alumina highly versatile.
Activated Alumina can easily be regenerated at elevated temperatures and pressures to restore its adsorption capacity, making it suitable for deployment in industrial settings with fluctuating process conditions, including natural gas processing plants that operate under fluctuating pressure levels. This flexibility reduces waste generation while simultaneously decreasing amounts needed per application – further contributing to sustainable practices.
Activated Alumina Powder
Activated alumina is a porous material composed of aluminium hydroxide that offers ample surface area to attract moisture molecules and absorb it, serving as an effective alternative to silica gel for dehumidifying packaging and products without altering their quality or functionality. It can also preserve freshness without compromise to their quality or functionality.
Under a microscope, activated alumina appears as spherical beads with microscopic tunnels running through them. Due to its porous and resilient composition, activated alumina can hold significant quantities of water within its tiny passageways – an ability which makes it an efficient adsorbent capable of trapping and eliminating many contaminants.
Activated Alumina is widely used as a desiccant to keep things dry by absorbing water molecules in air, but it’s also highly effective at removing fluoride, arsenic, selenium, and sulfur from drinking water supplies. Üstelik, its eco-cleansing applications extend well beyond these basic uses.
FEECO provides an expansive testing facility where activated alumina can be produced on both batch and pilot scale using rotary kilns, while also performing agglomeration tests with agglomerators, pin mixers and disc pelletizers to gather necessary process data for producing an agglomerate that will meet specific application goals. Our testing services serve to guarantee the end product meets expectations!
Activated Alumina Granules
Activated alumina is made up of aluminium oxide in the form of very porous spheres that have been microscopically tunnelled, making it highly versatile for many tasks. For instance, it can be used to dry gases such as propane or butane that might rust transport equipment, separate molecules apart, process chemicals like ethanol and carbon dioxide efficiently or even dry liquids such as water and larger petroleum products with great efficiency – ideal for use in petrochemical production processes to help ensure product purity.
Because it has such a large surface area, activated alumina is also ideal for purifying water by absorbing impurities such as arsenic and lead from drinking water supplies. Üstelik, activated alumina is non-toxic and inert so will not react with most chemicals; however it must be stored away from any sources of heat since high temperatures could result in degradation.
Dependent upon the needs of its end user, alumina may be transformed into various shapes such as beads or powder using tools like an agglomerator, pin mixers or disc pelletizer. Once in its desired form, alumina must be regenerated in order to restore its adsorption capacity.
Activated Alumina Filter Media
Activated alumina filter media is widely used in water filtration systems to reduce fluoride levels in drinking water, with its high surface area-to-weight ratio and many “tunnel-like” pores making it ideal for absorption.
Alumina can also be used to effectively filter water of contaminants such as arsenic, selenium and chromium that pose health threats. Clean, safe water is of critical importance.
These filters can also reduce the presence of organic liquids like LPG, propylene, aromatic solvents, gasoline and steam cracked liquids in hydrocarbon fluids, while also being effective at extracting sulphates from wastewater.
Activated alumina comes in various grades and specifications that must be selected according to the needs of an industry. For example, NMW treatment using calcinated activated alumina must undergo an initialisation process in order to protect itself from aluminium leaching out.
Activated alumina is an efficient way to remove fluoride from drinking water and can also be used in water filtration systems to lower levels of harmful contaminates, including Thallium. Üstelik, activated alumina is ideal for remediation applications including groundwater site cleanups and storm water protection where metals such as arsenic, zinc, silica copper and lead need to be reduced in concentrations.
