Activated alumina’s porous structure offers an incredibly large surface area and can absorb, hold, and release numerous substances with ease. Easy to adsorb, heat treatment makes activated alumina even more porous to enhance its ability to attract substances while remaining non-toxic, nonflammable, chemically resistant; water insoluble and organic solvent resistant it withstands high temperatures without degradation & wear & tear can only enhance these qualities further.
Process for purifying gas streams containing carbon dioxide as an impurity by adsorbing carbon dioxide onto activated alumina particles of specific surface area between 200-299 m2/g with at least 80% aluminum oxide, silicon oxide and iron oxide components as well as from 0.001%-7.25% alkali metal or alkaline earth metal oxide components is provided.
Dehydration of Natural Gas
Activated alumina is an innovative and highly efficient material for purifying gases and liquids. As a highly porous material with large surface area and pores, activated alumina absorbs chemicals, gasses, dust, air moisture vapors from its environment more effectively than any other substance can do.
Active Alumina’s ability to adsorb water molecules has proven indispensable in the natural gas industry, where its capacity to remove moisture-laden natural gas helps transport more safely to liquefaction and distribution plants and helps avoid pipeline corrosion. Außerdem, activated alumina is often utilized at petrochemical plants in order to remove moisture vapor from hydrogen streams to ensure they meet stringent quality standards.
Actived alumina’s unique porous structure makes it the ideal material for absorbing gasstream odors and meeting stringent environmental regulations. By effectively adsorbing sulfur compounds such as sulfides, activated alumina is also an ideal desiccant that regulates moisture, helping HVAC systems control mold and mildew growth and enhance indoor air quality.
FEECO’s spray pyrolysis process significantly expands the surface area of activated alumina, producing larger pores with uniform distribution. Außerdem, this method speeds drying times, reduces attrition rates and shortens column regeneration cycles, making it an ideal solution for dehydration of natural gas, petrochemical processing and other industrial applications where fast, efficient and environmentally-friendly drying is critical.
Removal of Moisture from Liquids
Activated alumina’s advantageous pore structure and adsorption properties make it a popular choice as a desiccant for drying fluid streams. Capable of absorbing moisture molecules from air or other gases, its use helps prevent hydrate formation which in turn protects pipelines and compression equipment against damage due to these ice-like structures obstructing flow.
As an effective solution for eliminating hydrogen sulfide (H2S) from gas streams, improving purification and helping uphold industry safety standards and regulatory compliance. Außerdem, as a claus catalyst it plays a pivotal role in sulfur recovery units by converting hydrogen sulfide to elemental sulfur and mitigating emissions.
Actived alumina has long been utilized as a reliable adsorbent in chromatographic separation processes, enabling precise moisture control and purifying liquids. Außerdem, activated alumina’s robust chemical and physical characteristics make it the perfect support material for catalytic reactions in oil refining and petrochemical production that promote efficiency and stability.
Given its many uses, activated alumina’s global market is growing quickly. To ensure optimal performance and select the product suitable to your application needs, factors like adsorption capacity, attrition resistance, pore size distribution and chemical reactivity should be carefully considered before purchasing an activated alumina product. Außerdem, proper handling procedures must be implemented when working with activated alumina such as wearing personal protective equipment to avoid irritations and respiratory issues when handling this adsorbent adsorbent.
Deodorization
Activated alumina is widely used for deodorizing gas streams to remove hydrogen sulfide molecules and help prevent corrosion in pipelines and industrial equipment, as well as maintain quality and performance of finished products. Due to its unique pore structure and high mechanical and thermal stability, activated alumina makes an excellent material choice in this application, as its absorbent properties absorb any potential sulfide molecules before they return back into the atmosphere.
Activated alumina has many applications in liquids and gases drying processes, including air drying, industrial air dryers and compressed air systems. By effectively absorbing moisture and volatile organic compounds from streams to prevent corrosion, freezing or malfunction of equipment.
Heating of hydrated alumina allows water molecules to escape while the crystal lattice breaks apart at planes of structural weakness, creating a porous structure with an extensive surface area. Adsorption rates for activated alumina vary significantly depending on pH; ideal capacities typically lie between 5.5 – 6.5.
Activated alumina has the capacity to absorb large volumes of moisture, making it an effective desiccant. Außerdem, its stability at high temperatures with losses on ignition of less than 1.1% means it can also be safely pneumatically transported without issue or degradation to its product. Macawber Engineering has extensive experience pneumatically conveying extremely friable activated alumina catalysts without issue or degradation to their product.
