Pseudo-boehmite is an important hydrated alumina material. After appropriate forming, drying, and calcination treatments, it can be used to prepare alumina materials with a relatively large specific surface area and well-developed pore structures. Therefore, it is widely used in the production of alumina catalyst supports. In hydrogenation catalysts, alumina supports not only serve to support […]

During long-term use, lube oil will gradually accumulate moisture, oxidation products, and other impurities that affect oil quality. In order to restore the performance of lube oil, industrial production usually uses filtration, adsorption, refining, and other methods for regeneration treatment. Among them, activated alumina, as a granular adsorbent material with a well-developed pore structure, can […]

For processes using granular adsorbents, particle size is one of the important parameters that needs to be considered when selecting activated alumina. Many purchasers will directly ask: “Which one is better, 0.5–1mm, 0.5–1.5mm, or larger particles?” In fact, there is no “best particle size” that is suitable for all lube oils, all equipment, and all […]
