During the actual purchasing process, many customers may encounter the following questions: Is larger activated alumina particle size always better? What are the differences between different particle sizes? How can the appropriate specification be selected according to equipment and process requirements? In fact, the particle size of activated alumina directly affects gas flow resistance, adsorption […]
Generally, products with an alumina (Al₂O₃) content above 90% (such as 92%, 95%, and 99%) are referred to as high alumina ceramic balls, while products with lower alumina content (such as 17%, 23%, 30%, and 45%) are classified as low alumina ceramic balls. A higher alumina content generally means higher mechanical strength, better high-temperature resistance, […]
Ceramic balls are widely used in catalyst support layers, packing layers, and reactor internals. However, performance varies significantly depending on the material; high-alumina ceramic balls, in particular, have increasingly become the preferred choice for many industrial users due to their excellent mechanical strength and corrosion resistance. So, what exactly distinguishes high-alumina ceramic balls from ordinary […]
In practical applications, the adsorption capacity of activated alumina often varies significantly under different operating conditions. So, precisely which factors influence the adsorption capacity of activated alumina? I. Specific Surface Area and Pore Structure Activated alumina possesses an abundance of micropores and mesopores; its adsorption capacity stems primarily from its vast internal surface area. Generally […]
I. Why do alumina catalyst supports pulverize and break? 1. Insufficient Mechanical Strength Alumina catalyst supports operate under high pressure, high flow rate, and continuous operation for extended periods. If the product itself lacks sufficient compressive strength, it is prone to: · Particle breakage · Edge wear · Surface pulverization · Bed collapse Some low-quality […]
What is PSA (Press Swing Adsorption) Activated Alumina? PSA is a high-performance adsorbent specifically designed for pressure swing adsorption (PSA) systems. It possesses a high specific surface area, excellent pore structure, and good mechanical strength. It can achieve efficient adsorption and desorption of moisture and impurities under varying pressure conditions, thereby ensuring the stable operation […]
I. What is PSA-Specific Activated Alumina? PSA-specific activated alumina is a porous adsorbent material made from high-purity alumina using a special process. Its abundant micropores and large specific surface area give it excellent gas and moisture adsorption capabilities. Compared to ordinary alumina materials, PSA-specific activated alumina has the following characteristics: High specific surface area, providing […]
Activated alumina powder and ordinary alumina powder are two common materials. Although both belong to alumina products, they differ significantly in structural properties, production processes, and application areas. Understanding these differences helps in making more appropriate choices during procurement and use. I. Differences in Structure and Physical Properties 1. Different Pore Structures Activated alumina powder […]
Working Principle of Potassium Permanganate Activated Alumina Potassium permanganate activated alumina is a gas purification material made by impregnating a porous activated alumina carrier with a potassium permanganate solution. It not only possesses the high specific surface area and strong adsorption capacity of activated alumina, but also the strong oxidizing properties of potassium permanganate. When […]
