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 […]
0.5–1mm Activated Alumina is a granular adsorbent material with a porous structure and a large specific surface area. Compared with larger particles, the 0.5–1mm particle size can, to a certain extent, balance adsorption contact efficiency, bed operation, and mechanical handling requirements, and therefore has application value in some lube oil regeneration and refining processes. The […]
