Alumina is an extremely porous material composed of numerous microscopic tunnels which enable it to absorb substances, making it a fantastic material for industrial processes and applications.
Desiccant powders can be used as desiccants in water treatment systems to remove fluoride, arsenic and selenium contaminants that pollute drinking water supplies; while also serving to filter harmful gases and chemical vapors from indoor environments.
High Surface Area
Alumina boasts exceptional adsorption capabilities due to its unique structure containing an abundant pore network, which allows it to absorb various substances such as water, chemicals and gases. Due to this characteristic it has become an invaluable component for industrial uses like water treatment and desiccant applications.
G-alumina has proven itself as an efficient adsorbent of contaminants found in drinking water sources, such as fluoride, arsenic and selenium. Furthermore, it serves as an effective water adsorbent in industrial settings by helping remove moisture from compressed air so as to avoid equipment damage while upholding product quality standards.
Alumina’s high surface area can be attributed to its activation process, which produces a porous structure full of pores and channels, allowing moisture molecules to adhere more readily, thus increasing its absorption capabilities relative to silica gel.
Alumina’s porous structure makes it highly resistant to corrosion caused by metallic impurities, making alumina an excellent catalyst carrier and adsorbent in various applications in the petrochemical industry.
Selective Adsorption
Alumina’s porous structure allows it to absorb materials attracted to its surfaces and channels, effectively removing impurities and moisture from liquids, gases, and air. Alumina is commonly used as a desiccant, or drying agent, in industrial settings to remove moisture buildup that would otherwise lead to costly equipment downtime due to moisture buildup.
Activated alumina can serve as an efficient air purifier, filtering out hazardous airborne chemicals and allergens from indoor environments. As such, activated alumina is often found in heating, ventilation, and air conditioning (HVAC) systems in order to help combat mold growth or other indoor air quality issues.
As a desiccant, alumina acts to absorb moisture from the air before releasing it when heated at high temperatures. This method is often referred to as reverse osmosis desiccants and differs from silica gel which adsorbs water molecules using different mechanisms.
Adsorption technology also helps protect products and equipment from moisture-related damage, particularly in petrochemical settings where excess moisture can cause corrosion of processing and storage facilities. Gas dehydration applications benefit greatly from using alumina’s versatile adsorption capabilities – protecting natural gas streams from degradation along pipelines – while its flexible application ensures its continued use by numerous industries around the globe.
High Crush Strength
Activated alumina is a non-toxic, tasteless porous material that’s not affected by water or most chemicals, making it suitable as an adsorption desiccant or catalyst carrier.
Compared to silica gel, activated alumina is much more durable. Its granular form provides high crush strength and can withstand strain from industrial applications – making it the perfect material choice for air drying and dehumidification applications.
Filtration uses of silica gel include filtering at low dew points to prevent corrosion, rust and other damage in pipelines and processing equipment, while its highly effective polar adsorbent properties allow it to attract molecules of high polarity, making it suitable for column chromatography.
FEECO’s Innovation Center offers continuous process loop testing using activated alumina’s high crush strength and low dust content, making it the ideal candidate for continuous process loop testing. Testing can be conducted both batch and pilot scale to find you a tailored solution.

Versatility
Activated alumina has applications in numerous industrial processes. When processing natural gas, activated alumina serves as an efficient desiccant to dehydrate natural gas before liquefaction and transportation, helping avoid pipeline corrosion and preserve pipeline integrity. Furthermore, activated alumina chemically reacts with hydrogen sulfide present in natural gas streams to meet stringent purity standards for H2S purity levels.
Packaging applications often employ humidity barriers like polyethylene as moisture barriers. Adsorbing harmful moisture molecules, this material prevents degradation and extends shelf life for products such as grains, seeds, flowers and foodstuffs. Furthermore, HVAC systems use it to control humidity levels indoors while also absorbing potentially hazardous chemical vapors that accumulate.
Manufacturers can easily adjust the pore size and surface area of activated alumina by altering temperature settings and the components used during its activation process, such as aluminium hydroxide or other aluminium compounds. This enables them to tailor activated alumina adsorbents for specific applications while optimizing performance while decreasing operating costs.
Molecular sieves and silica gel, however, only perform adsorption at one temperature; activated alumina is more adaptable in that it can be chemically regenerated for use at multiple temperatures to remove H2S gas emissions, saving both money and time by eliminating the need to purchase new material. Furthermore, its regenerability contributes towards sustainable production practices by reducing waste generation while complying with sustainable production requirements. To achieve maximum performance from activated alumina it should be stored in sealed containers protected from excessive heat while handled carefully to avoid premature water absorption.
