1、Drying and purification of activated alumina gas

Deep drying: Acetylene, hydrogen and other gases can be dried to a dew point below -55°C, which is suitable for heat-free regeneration devices.

Air purification: As a pre-adsorbent of molecular sieve, remove H₂O and CO₂ to ensure the purity of subsequent processes.

2. Water quality treatment of activated alumina

Fluorine removal: The adsorption capacity reaches 5 mg/g, and the treatment cost is about 3-10 cents/m³ of water. It is widely used in drinking water safety engineering.

Decolorization and odor removal: remove phosphates, organic matter and color, and improve industrial wastewater discharge standards.

3. Catalysis and separation of activated alumina

Catalyst support: Supported precious metals (such as Pt and Pd) are used for petroleum hydrocracking and automobile exhaust purification, and the pore structure promotes the diffusion of reactants.

Chromatographic separation: Separate organic matter such as aromatic hydrocarbons, alkaloids, and neutral alumina has the widest application.

4. Special fields of activated alumina

Oil maintenance: removes organic acids and precipitates from engine oil and prolongs the life of the equipment.

Container drying: prevents moisture and rust in ocean-going transportation, and the moisture absorption rate can reach 250% of its own weight.
