What Are the Advantages of the Low Sodium Characteristics of PSB-LOW-NA? An important feature of PSB-LOW-NA produced by Zibo Xiangrun is the control of Na₂O content, and the Na₂O indicator can reach ≤0.10%. Why do catalyst production enterprises pay attention to this indicator? Pseudo-boehmite can be converted into alumina materials through subsequent processing, and impurity […]
Pseudo-boehmite usually needs to undergo processes such as forming, drying, and calcination to be converted into an alumina support. During this process, the sodium element in the raw material may affect the surface properties of the final alumina. For catalysts, the alumina support does not only serve the role of “support.” It also needs to […]
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 […]
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 […]
Activated alumina is a material with a porous structure, and its numerous pores and large internal surface area give it good adsorption and loading capabilities. This characteristic is also one of the important reasons why it is used as a catalyst carrier. However, at the same time, the porous structure means that the material is […]
What Kind of Activated Alumina Catalyst Support Can Be Considered Good Quality? Activated alumina catalyst support is mainly used to carry active components and provide suitable surface and pore structure for catalytic reactions. Therefore, judging its quality cannot only depend on whether the “alumina content is high” or whether the “specific surface area is large.” […]
During the actual purchasing process, some customers often first focus on the specific surface area and pore volume of activated alumina catalyst support, while mechanical strength is easily overlooked. However, for industrial catalytic units that need to operate for a long time, mechanical strength is directly related to the stability of the support during transportation, […]
During the production of hydrogen peroxide, activated alumina is a commonly used adsorbent material. For enterprises that need to purchase or replace activated alumina, in addition to paying attention to indicators such as adsorption performance, mechanical strength, and bulk density, particle size is also a very important selection factor. There are various particle size specifications […]
