Activated alumina is used as a desiccant in compressed air compression systems, due to its intricate network of pores providing ample surface area for moisture absorption. Granules typically form either round or cylindrical shapes when activated alumina is processed and put into use as a desiccant.
F200 activated alumina is designed to absorb highly polar molecules such as water and alcohol more readily. Additionally, it can absorb degradation acids found in transformer oils, lubricants, and refrigerants.
adsorption capacity
Activated alumina is an extremely porous material capable of absorbing a great amount of water. Although all molecules adsorb some amount, water molecules have the highest affinity with activated alumina and is non-toxic and safe for industrial applications. Adsorption capacity will depend upon conditions under which activated alumina is operated; to make an informed decision when selecting your material.
Alumina beads differ from sand in that they possess many micropaths which enable them to absorb large volumes of water and act as desiccants and catalyst carriers. Furthermore, due to its high specific surface area and use in defluorinating gases and desiccant applications such as coal gasification processes.
BASF F200 Alumina Beads feature uniform sizes, which makes them an excellent choice for high-pressure gas dehydration with minimal pressure drop. Their sphericity prevents segregation during pneumatic loading and channeling while the beads’ resistance to amine attack and high crush strength make this product even more useful.
Adsorption capacity of alumina is determined by its ability to attract and trap water molecules in an polarized state. While all molecules will eventually adsorb onto it to some degree, more polar ones tend to preferentially adhere to its surface; this process depends on stream conditions, temperature and the molecular weight of each of these molecules.
sphericity
Activated alumina is produced by dehydroxylating aluminium hydroxide to produce a porous material with an increased surface-area-to-weight ratio, known as activated alumina. This substance can then be used as a desiccant (to absorb excess moisture in order to keep things dry) as well as for filtering drinking water of fluoride, arsenic, and selenium contaminants; additionally it has the capability of adsorbing pollutants like sulphides or sulfur dioxide from fluid streams.
Activated alumina differs significantly from corundum in that it contains many chemically active sites that make it suitable for adsorption and catalysis, unlike corundum which contains only stable forms of aluminum oxide. Regeneration with sodium hydroxide solutions (NaOH) or sulfuric acid solutions (H2SO4) may allow regeneration; depending on the conditions it can remove up to 10ppm of fluoride.
F200 Spherical Alumina Desiccant is an economical, industrial-grade desiccant that provides cost-effective dehydration of gases and liquids. Featuring uniform ball size – which reduces pressure drop during high-pressure gas dehydration – and tailored pore distribution, its dynamic adsorption capacity is unparalleled. Furthermore, with high crush strength resistance against amines it makes an excellent solution for dehydrating acid-containing streams.
F200 adsorbed all molecules to some degree; polar molecules were particularly well absorbed. Adsorption is affected by stream conditions such as concentration and molecular weight of molecules entering, temperature, site competing molecules and site competition between competing molecules in a stream. Interra Global provides BASF F-200 Spherical activated Alumina in sizes 1/16″, 3/16″ and 1/4″. These sizes are perfect for reducing fluoride levels in drinking water supplies; adsorbing catalysts used in polyethylene production processes, air separation/drying as well as defluorination/defluorination.
high crush strength
F200 activated alumina is an economical, high-performance desiccant used to dry air and other gas streams in compressed air dryers. Featuring large pores with high surface areas, chemical stability, non-toxicity, non-odorance and tastelessness it makes an excellent alternative to silica gel and molecular sieves in many situations, as well as occasional usage where their performance limitations exist.
BASF F-200’s spherical shape and uniform size prevent segregation of adsorbent during pneumatic loading, thus minimizing channeling and making more efficient use of desiccant tower space. Furthermore, its high crush strength enables it to be used in taller towers for optimal space utilization and its resistance to amine attack gives F-200 an extended operating lifespan as it dehydrates acid-containing gases and liquids such as CO2.
BASF F-200’s low abrasion ensures less dusting during transport, loading, and service; this in turn reduces pressure drop as well as downstream valve and filter plugging associated with dustier products. Furthermore, its large surface area and tailored pore distribution provides high dynamic dew point adsorption capacity; making it suitable for dehydrating gases both thermally regeneratively as well as pressure swing adsorption modes (PSA).
resistance to amines
Activated alumina (Al2O3) is a porous form of aluminum oxide (Al2O3) with an increased surface-area-to-weight ratio due to the many “tunnel-like” pores it contains, making it suitable for many uses, from desiccant and fluoride filtering applications, to chemical processing adsorbent use such as catalyst removal during polyethylene production and removal of sulfur from fluid streams; additionally it’s used in fluoride and arsenic removal from drinking water sources before regeneration with either NaOH (sodium hydroxide; NaOH) or H2SO4 treatment methods.
BASF F-200 spherical activated alumina is designed to selectively absorb highly polar molecules. Available in sizes 1/8″, 3/16″, and 1/4″, this material can be used for drying gases and liquids such as transformer and lubricating oils, refrigerant systems, or any application where low dew points are essential.
F-200 Alumina’s sphericity and uniform size prevent segregation during pneumatic loading, thus maximizing channeling efficiency and improving overall usage of its desiccant tower. Furthermore, this material’s resistance to amine attack allows taller towers for faster dehydration processes as well as being suitable for acid containing gases/liquids such as CO2. Furthermore, F-200 has lower temperature degradation compared to corundum as well as better resistance against water attack, making it an excellent choice for CO2 capture applications.
