Many customers ask a question when selecting activated alumina: Is smaller particle size of activated alumina for air separation equipment better? Under certain conditions, smaller activated alumina particles can indeed shorten the mass transfer distance for moisture entering the particles and help improve the mass transfer rate. However, for air separation equipment and fixed-bed adsorption […]
Why Does Activated Alumina Produce Dust? Activated alumina is usually loaded into the adsorption bed in the form of spherical particles. During transportation, loading and unloading, and equipment operation, collisions and friction may occur between the particles. If the mechanical strength of the activated alumina is insufficient, or if the particles themselves contain a large […]
Activated alumina is usually filled in the adsorption bed in spherical or approximately spherical particles. When compressed air or feed air passes through the adsorbent bed, the moisture in the air comes into contact with the activated alumina particles and is adsorbed by the pores. Particle size will directly affect the flow state of the […]
Why Is Potassium Permanganate Activated Alumina Affected by Humidity? When the moisture in the gas increases, water molecules also interact with the surface and pores of activated alumina. If the humidity is at a relatively high level, water may occupy part of the surface and pore space, causing changes in the ability of target pollutants […]
Spherical particles have a relatively regular shape and, with relatively uniform particle sizes, are more likely to form a stable adsorbent bed. For potassium permanganate activated alumina, this is particularly important because its actual performance depends not only on the chemical properties of the material itself, but is also closely related to the residence time […]
How Does Activated Carbon Remove Odors? Activated carbon has a developed pore structure and a large specific surface area, and can capture various pollutants in the air through physical adsorption. When air containing odor gases passes through the activated carbon bed, some pollutants enter the pores inside the activated carbon and are adsorbed on its […]
Potassium permanganate is an important active component in potassium permanganate activated alumina. For certain reducing pollutants and odorous gases, potassium permanganate can exert an oxidizing effect. Therefore, a reasonable potassium permanganate loading is very important for the purification performance of the material. When the potassium permanganate content is relatively low, the active components that can […]
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 […]
