Activated alumina powder is not simply ordinary alumina powder. Activated alumina prepared through specific processes has a well-developed pore structure and a relatively large specific surface area. These characteristics enable it to provide more loading sites for catalyst active components. After forming, calcination, and other processes, activated alumina powder can be made into alumina supports […]
Pseudoboehmite is a hydrated alumina material. It has good peptization properties, a relatively high specific surface area, and an adjustable pore structure, so it is widely used in alumina materials, catalyst supports, and adsorbent materials. Compared with ordinary alumina, an important characteristic of pseudoboehmite is that its structure contains a certain amount of bound water. […]
Large pore volume pseudo-boehmite is a type of pseudo-boehmite product characterized by a relatively large pore volume. For some catalyst support and industrial alumina applications, a larger pore volume can provide more sufficient internal pore space, so large pore volume pseudo-boehmite has attracted the attention of many industrial customers. However, it should be noted that […]
Many buyers usually focus first on price, Al₂O₃ content, and specific surface area when selecting pseudo-boehmite. However, there are many other factors that can have a real impact on subsequent processing and the performance of the final product, such as pore volume, pore size distribution, impurity content, particle size, moisture content, and batch-to-batch consistency. So, […]
A catalyst support needs to meet several requirements, such as having an appropriate pore structure, a large surface area, good thermal stability, and certain mechanical strength. Pseudo-boehmite can provide a good foundation for these properties. Large Specific Surface Area One important role of a catalyst support is to provide sufficient loading space for active components. […]
Pore volume is an important parameter for evaluating the pore structure of pseudo boehmite. It usually represents the volume occupied by pores inside the material per unit mass. Simply put, the larger the pore volume, the more space the material can provide internally, and the alumina support formed generally has a richer pore structure. In […]
Excessive Pollutant Concentration Accelerates Adsorbent Deactivation Potassium permanganate activated alumina has a certain treatment capacity, and the amount of pollutants that can be treated per unit mass is limited. When the concentration of harmful gases entering the adsorption tower continuously exceeds the designed range, the active components will be consumed more rapidly, resulting in a […]
Different particle sizes of potassium permanganate activated alumina are suitable for different types of equipment. If the particle size is not selected properly, even a high-performance product may lead to increased system pressure drop, uneven airflow distribution, reduced purification efficiency, and even a shorter service life of the adsorbent. Therefore, before purchasing, selecting the appropriate […]
Conventional adsorbents mainly rely on physical adsorption to remove pollutants, while potassium permanganate activated alumina is produced by uniformly impregnating high-quality activated alumina with potassium permanganate, enabling the material to possess both physical adsorption and chemical oxidation capabilities. As exhaust gas passes through the adsorption bed, harmful gases are first adsorbed onto the surface of […]
Activated carbon mainly relies on its well-developed pore structure and large specific surface area to adsorb pollutants onto the material surface through physical adsorption. As the adsorption sites gradually become saturated, its adsorption capacity decreases, and the material needs to be replaced or regenerated. Potassium permanganate activated alumina is produced by uniformly impregnating potassium permanganate […]
