Activated alumina is a dry, granular form of aluminum oxide with an affinity for water molecules. This makes it suitable for desiccant applications such as air drying or filtering out fluoride, arsenic and selenium from drinking water supplies.
BASF F-200 Spherical Activated Alumina is an industry leader when it comes to compressed air drying, thanks to its tailored pore distribution, high dynamic water adsorption capacity and lower desorption temperatures – offering significant energy cost savings over competing solutions.
Activated alumina
Activated alumina is a highly porous material widely used for industrial and environmental applications. Made from aluminium oxide (Al2O3), activated alumina undergoes an activation process to form an extensive network of pores with high surface area – making it an efficient adsorbent and leading to its widespread usage across various industries.
One of the primary applications for activated alumina is as a desiccant, helping remove ambient moisture from the air to protect sensitive materials from corrosion and other forms of damage caused by moisture accumulation. This application is especially useful for electronic components that are susceptible to moisture-induced failure, like semiconductors. Hơn nữa, activated alumina can also be used as an efficient gas purification agent such as hydrogen peroxide or natural gas purification systems.
Actived alumina not only absorbs moisture, but it can be impregnated with chemical solutions that increase its capacity to absorb other substances as well. This process, known as sizing, typically takes place in batch or pilot-scale kilns, and may involve testing various agglomeration techniques and potential biners.
Activated alumina is an ideal material to use when packaging electronic devices, providing an optimal dry environment within its packaging to minimize corrosion risk and short circuiting risk. Hơn nữa, its adsorption capacity can be restored through use of appropriate chemicals which enable manufacturers to comply with Good Manufacturing Practice and Hazard Analysis and Critical Control Point regulations.
DD-6
DD-6 activated alumina is produced through the thermal decomposition and activation of aluminum trihydroxide (gibbsite). Its high surface area and porosity make it highly effective at attracting polar molecules for adsorption, making DD-6 an attractive alternative to molecular sieves for compressed air drying applications where very low dew points down to -100 degC/-150 degF are desired. Molecular sieves typically have greater affinity to water than activated alumina, thus necessitating higher regeneration temperatures (typically 230-290 degC) for effective moisture expulsion.
Activated alumina is widely utilized as a desiccant for compressed air drying in industries like petrochemical, natural gas processing and mining. Additionally, it serves as a filter against fluoride, arsenic, and selenium contaminants found in drinking water sources. Due to being non-toxic and stable in handling applications; additionally it has resistance against amine attack allowing its use in high pressure gas dehydration systems.
BASF F-200 activated alumina offers superior performance for desiccant air dryers. Its uniform size ensures moisture doesn’t absorb during pneumatic loading and tower filling times are greatly decreased as a result of improved flowability and reduced channeling; its sphericity enhances flowability for greater desiccant tower utilization; furthermore it boasts high crush strength as well as being resistant to amine attack; making this an excellent choice even in demanding applications.
Sorbead
Sorbead from BASF is an amorphous aluminosilicate gel with unique properties that makes it the ideal H2O adsorbent for carbon capture and storage (CCS). It meets pipeline specifications while offering lower energy costs, lower lifetime costs, and superior lifetime performance compared to alternative CO2 drying solutions. Hơn nữa, BASF’s expertise, products, technologies, and reliable support help customers optimize their performance and profitability.
Sorbead Air line of highly efficient adsorbents are used for dehydration of technical gases and liquids as well as drying compressed air, with hard, spherical beads made of alumino silicate gels forming hard and resistant beads with low attrition rates. Their above average drying capacities also require lower desorption energy costs.
Sorbead stands out from molecular sieves by having superior mechanical strength and being regenerable at much lower temperatures, as well as being stable under low dewpoint temperatures and cryogenic conditions, making it suitable for CO2 capture applications where high regeneration temperatures limit available adsorbent options.
Sorbead Air WS is water stable and ideal for use as a guard layer in combination with Sorbead Air R beds to protect them from liquid water carry-over. Hơn nữa, its moisture repelling properties also make it suitable for other adsorbents and catalysts used in applications like power transformer breathers.
