Fundamental Principles of Activated Alumina and Molecular Sieves Activated Alumina Activated alumina is a porous alumina adsorbent characterized by a high specific surface area and excellent hygroscopic properties. Internally, it possesses an abundant microporous structure that enables it to rapidly adsorb moisture from the air through physical adsorption. Key Features: · Strong water adsorption capacity […]

With the growing demand for large-scale air separation units, high-pressure oxygen generation systems, and continuous production operations, traditional adsorbents are increasingly unable to meet the requirements for long-cycle operation; consequently, high-strength activated alumina is becoming the preferred choice for a growing number of air separation enterprises. Why is air pretreatment essential for air separation units? […]

In catalytic systems, inert alumina ceramic balls serve as both bottom support layers and capping materials, playing a crucial role in supporting the catalyst, ensuring uniform distribution of gas and liquid flows, and protecting the reactor. Compared to ordinary ceramic materials, high-performance alumina ceramic balls—distinguished by their exceptional mechanical strength, high-temperature resistance, and chemical stability—have […]
