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 elements in the raw materials may affect the surface properties of the final alumina and the catalyst system. For some catalyst systems with high requirements for raw material purity, controlling the sodium content can provide a more stable raw material basis for subsequent material performance control.
Especially in applications such as hydrotreating catalysts and catalyst supports, alumina supports need to take into account surface properties, pore structure, active component dispersion, and mass transfer performance. Therefore, production enterprises usually do not focus on only one indicator, but need to comprehensively control the chemical composition and physical properties of the raw materials.
High Specific Surface Area Provides a Good Structural Basis for Alumina Materials
In addition to Na₂O, specific surface area is also an important indicator for evaluating pseudo-boehmite.
The specific surface area of Zibo Xiangrun PSB-LOW-NA can reach ≥260 m²/g. A larger specific surface area means that the material has a more abundant surface area, which is of great significance for the subsequent preparation of high-specific-surface-area alumina materials.
Pseudo-boehmite can form transition alumina after calcination, among which γ-Al₂O₃ is widely used as a catalyst support because of its large specific surface area and good pore structure. For catalysts, the pore structure of the support not only affects the loading of active components, but also affects the mass transfer process of reactants in the pores.
Therefore, for enterprises that need to produce high-performance alumina catalyst supports, choosing pseudo-boehmite with a stable specific surface area can provide a better basis for subsequent material structure design.
Appropriate Pore Volume Helps with Subsequent Pore Structure Regulation
Pore volume is also one of the important indicators of PSB-LOW-NA, with a pore volume range of 0.3–0.5 mL/g.
The pore structure of pseudo-boehmite is affected by preparation conditions and subsequent treatment processes. Studies have shown that the specific surface area, pore volume, and pore size of pseudo-boehmite can be adjusted through preparation conditions, and these structural characteristics are of great significance to the application performance of the final alumina material.
For catalyst support production enterprises, an appropriate pore volume means that the raw material has a basis for further pore structure design and regulation. Especially when preparing γ-Al₂O₃ catalyst supports, the pore structure needs to be matched according to the specific reaction system and active component requirements, rather than simply pursuing a higher value for a particular indicator.
What Applications Is PSB-LOW-NA Suitable For?
With low Na₂O, relatively high specific surface area, appropriate pore volume, and good peptization performance, PSB-LOW-NA can be used as an important raw material for preparing alumina materials, especially for catalyst and alumina-related applications that have certain requirements for raw material performance.
In the production of hydrotreating catalysts and catalyst supports, pseudo-boehmite is generally used as a precursor for alumina supports. The performance of the final catalyst depends on multiple factors, including support pore structure, active component dispersion, surface properties, and preparation conditions. Therefore, stable pseudo-boehmite raw materials can provide a more reliable foundation for subsequent production.
