High temperature resilience: It maintains its integrity and performance in high-temperature environments.
High crush strength: This physical attribute makes it resistant to damage and wear, crucial for its use in industrial-scale drying and adsorption systems.
Low dusting: Activated alumina produces very little dust, which is essential for applications requiring strict purity standards and to prevent contamination.
High adsorption capacity: Activated alumina has a vast network of pores, creating a high surface area that efficiently captures molecules like water, oils, and specific contaminants.
Porous structure: The high porosity allows for the adsorption and retention of gases and liquids within its internal channels and voids.
Selective adsorption: It demonstrates precision in targeting and removing specific impurities, such as fluoride from drinking water or h₂s from gas streams.
Chemical stability: Activated alumina is chemically inert, meaning it resists degradation when exposed to various chemicals and gases, ensuring reliable performance.
Application of Activated Alumina Adsorbent
Gas drying (dehydration):
The porous structure of activated alumina has a strong affinity for water molecules. It can adsorb moisture in the gas under high pressure and be desorbed and regenerated under low pressure.
Removal of acidic gases:
Activated alumina can adsorb acidic gases such as carbon dioxide (CO₂) and hydrogen sulfide (H₂S).
Separation and purification of other gases:
In small-scale PSA oxygen generation equipment, activated alumina can be used in combination with molecular sieves to preferentially adsorb trace impurities in nitrogen (such as water, CO₂), and assist in improving the purity of oxygen.
Hydrogen purification:
Adsorb water vapor and organic impurities in hydrogen to ensure that the purity of hydrogen meets the requirements of chemical engineering (such as hydrogenation reactions) or energy (such as fuel cells).
Production Process of Activated Alumina Adsorbent
Raw material preparation: The raw material used in the production of activated alumina is typically aluminum hydroxide. The aluminum hydroxide is processed to remove impurities and then ground into a fine powder.
Activation: Activation involves subjecting the powder to temperatures nearing 1000°c. This high-temperature treatment causes the aluminum hydroxide to undergo a phase change and transform into gamma alumina, which has a larger surface area and greater porosity.
Impregnation: After activation, the gamma alumina is impregnated with a chemical solution that enhances its moisture-adsorbing properties. Common impregnating agents include phosphoric acid, potassium permanganate, and sodium hydroxide. The choice of impregnating agent depends on the specific application of the activated alumina.
Drying and packaging: The final step in the manufacturing process is drying and packaging the activated alumina desiccant. The impregnated gamma alumina is typically dried in a rotary kiln to remove any residual moisture. The dried activated alumina is then packed in bags or drums and shipped to customers.
