Main applications of 1-1.5mm activated alumina

2025-11-11

1-1.5mm activated alumina plays a vital role in numerous industries due to its perfect balance between adsorption capacity, mechanical strength, and system pressure drop. If you are looking for an efficient and reliable medium to solve drying, purification, or catalytic challenges, you can learn more about this size of activated alumina.

Core Application Areas

1. Deep Drying of Gases and Liquids

Activated alumina has a highly hydrophilic surface, enabling it to deeply capture moisture and achieve extremely low dew points.

Air Separation Industry: Before compressed air from oxygen and nitrogen production enters the cryogenic separation unit, activated alumina is used for deep drying to prevent moisture from freezing and clogging equipment and pipelines, ensuring the safe and stable operation of the air separation unit.

Industrial Gas Drying: Used for drying instrument air, protective gases (such as H₂, N₂), and petrochemical feedstock gases such as ethylene and propylene, ensuring the purity of downstream processes and the corrosion protection of equipment.

Organic Solvent Dehydration: Used in the petrochemical and pharmaceutical industries for the deep dehydration of solvents such as ethanol, benzene, and gasoline.

2. As a Highly Efficient Catalyst Support

Hydrogen Peroxide Production: In the anthraquinone process for producing hydrogen peroxide, 1-1.5mm activated alumina serves as a support for palladium catalysts, used in the hydrogenation working fluid, and is the core of the entire production chain.

Petrochemicals and Hydrorefining: In refineries, it is widely used as a support for catalysts in hydrodesulfurization and hydrocracking.

Clause Sulfur Recovery: In the Claus process for desulfurization of natural gas and refinery gas, it acts as a catalyst, promoting the conversion of hydrogen sulfide into elemental sulfur, achieving sulfur resource recovery and environmentally friendly emissions.

3. Water Treatment and Defluoridation

Drinking Water Defluoridation: Activated alumina can safely and effectively adsorb and remove excess fluoride ions from water, preventing endemic fluorosis.

Industrial Wastewater Treatment: It can be used to adsorb harmful anions such as phosphate and arsenate in wastewater, achieving deep purification and compliant discharge of industrial wastewater.

4. Other Specialized Applications

In addition, it plays a role in some specific fields: chromatographic separation, biodiesel purification, etc.

Why choose the 1-1.5mm specification?

Optimal mass transfer efficiency: Easier to handle than powder, provides a larger contact area than larger particle sizes, resulting in faster reaction and adsorption rates.

Suitable system pressure drop: In a fixed bed, it ensures smooth fluid flow without the excessive pressure drop seen with smaller particle sizes, thus reducing energy consumption.

Excellent mechanical strength: Wear-resistant and crush-resistant, it is not easily pulverized under repeated adsorption-regeneration cycles or high-pressure conditions, extending its service life.

Whether you need to solve demanding deep drying problems, find a highly efficient and reliable catalyst carrier, or seek a safe defluoridation solution for drinking water, it is a proven and wise choice.
