When it comes to 0.5-1mm activated alumina, many people immediately think of it as an excellent catalyst support. Indeed, its regular particle size, high surface area, and strong mechanical strength make it a key player in petrochemicals and chemical synthesis. But in what other fields does 0.5-1mm activated alumina play a vital role?
Gas Purification:
1. Desiccant
Its surface possesses numerous polar active centers, which strongly adsorb highly polar water molecules, thereby removing water vapor from wet gases.
Applications:
Compressed Air and Gas Drying: Removes moisture from compressed air to prevent pipeline corrosion, instrument damage, and other problems in certain applications.
Natural Gas and Petrochemical Industries: Deeply removes moisture from natural gas before transportation and processing to prevent hydrate formation and ice blockage under high-pressure, low-temperature conditions and to meet pipeline transportation standards.
Industrial Cracking Gas Drying: Deeply dry gases such as ethylene and propylene.
Air Separation Units: Deeply dry air before separating it to produce oxygen and nitrogen to prevent moisture from freezing at low temperatures and clogging equipment and pipelines.
2. Adsorbent
In addition to absorbing water, activated alumina can also selectively adsorb certain polar molecules and acidic substances.
Adsorption of Acidic Substances:
HF (Hydrogen Fluoride) Removal: In processes such as alkylation and fluorine chemical processing, it can effectively remove HF from gases.
HCl, SOx, and Other Gas Removal: Under certain conditions, it can be used to remove other acidic gases.
Selective Adsorption: In certain processes, it can be used to separate gas mixtures, for example, by utilizing its strong adsorption for water and other polar molecules for separation and purification.
Water Treatment:
In many regions of the world, high levels of fluoride in drinking water pose a serious health threat. Activated alumina is recognized as a highly effective fluoride removal material.
Applications:
Community drinking water treatment plants: Used as a filter media, it effectively reduces fluoride levels in water to below safety standards.
Industrial Fluoride Wastewater Treatment: Treats fluoride-containing wastewater discharged from industries such as electronics, electroplating, and glass, ensuring compliance with environmental standards.
Why is 0.5-1mm the "golden specification"?
High surface area: Provides ample adsorption sites for high efficiency.
Low bed pressure drop: Ensures minimal resistance to fluid flow, reducing energy consumption.
Strong mechanical strength: Resists wear, resists pulverization, and offers a long service life.
Excellent mass transfer performance: Rapid adsorption and desorption rates.
These properties make 0.5-1mm activated alumina a star material in the adsorption, separation, and purification fields.
