Q1: What is the difference between boehmite and ordinary aluminum hydroxide?
The core difference lies in their structure and performance orientation:
Boehmite: Low crystallinity, high specific surface area, suitable as a catalyst support.
Ordinary aluminum hydroxide: High crystallinity, low specific surface area, more suited for basic filler applications.
If the application involves catalytic activity, lifetime, or stability, ordinary aluminum hydroxide usually cannot meet the requirements.
Q2: In which industries is pseudoboehmite mainly used?
Pseudoboehmite is mainly used in the following fields:
Petroleum refining and petrochemical catalysts
Hydrodesulfurization, denitrification, and hydrocracking catalyst support
Activated alumina adsorbents and desiccants
Fine chemical and environmental protection catalytic materials
Especially in catalytic systems requiring high specific surface area and metal dispersion, pseudoboehmite is almost always the preferred raw material.
Q3: What is low-sodium boehmite?
Low-sodium boehmite refers to boehmite products with strictly controlled Na₂O content.
Sodium impurities can poison catalysts; therefore, low sodium content is particularly critical in refining and precious metal catalytic systems.
Q4: Why is sodium content so important for catalysts?
Excessive sodium content can lead to:
Decreased dispersion of active metals
Reduced catalytic activity
Shortened catalyst lifetime
Therefore, high-end catalyst supports typically require the use of low-sodium boehmite to ensure long-term stability of catalytic performance.
Q5: What are the key technical indicators of pseudoboehmite?
When selecting a catalyst, it is recommended to focus on the following parameters:
Specific surface area (BET)
Pore volume and pore size distribution
Na₂O content
Loss on ignition (LOI)
Particle size and dispersibility. The requirements for these indicators vary significantly depending on the catalytic reaction and molding process.
Q6: Can pseudoboehmite be customized?
Yes.
Professional manufacturers can usually adjust the following parameters according to customer needs:
Specific surface area range
Pore structure design
Sodium content control
Particle size and dispersibility. Customized pseudoboehmite is more beneficial for improving the final performance of the catalyst than simply using a generic model.
Q7: How do I determine if pseudoboehmite is suitable for my project?
We suggest you clarify the following questions before purchasing:
Will the final product be used as a catalyst support?
Are there specific restrictions on sodium content?
Is a specific specific surface area or pore size structure required?
Only by considering the specific application can you select the truly suitable pseudoboehmite model.
