Description
The low sodium activated alumina is activated alumina (γ-Al2O3) powder developed independently from low-sodium boehmite, and has partially replaced low-density low-porosity low-sodium hypothesized thin water in the field of coal chemical catalysts. Alumina, compared with low-density small hole pseudo-boehmite, has greater quality and cost advantages, with the advantages of pure crystal phase, low sodium content, narrow particle size distribution, and controllable particle size. It is mainly used as a catalyst and catalyst carrier for automotive exhaust gas purification, petrochemical industry, coal chemical industry, and high purity activated alumina for catalysts and carriers such as ZSM, FCC, and SAPO.

Activated alumina application:
How to remove the sodim in alumina？ How to get Low Sodium Activated Alumina?
At present, the common sodium removal processes mainly include the following: one in kind
Increasing the particle size of aluminum hydroxide crystals and increasing the washing power in stages
Degree and other methods to reduce the sodium oxide content in industrial aluminum hydroxide, from
Indirectly reducing the content of sodium oxide in alumina can generally be reduced to
0.2%; Second, it is calcined into α-alumina with aluminum hydroxide as raw material
In the process, by increasing the amount of additives and appropriately increasing the calcination temperature
To reduce the sodium oxide content in the product. The method is easy to implement,
However, the energy consumption is high, the exhaust gas emissions are large, and the application performance of the product is limited; three
Sodium is removed by wet hydrothermal treatment, and the sodium oxide content can be reduced to
0.05%, the advantage of this method is that it can effectively reduce the content of industrial alumina
The content of sodium oxide, the disadvantage is that the intermediate semi-finished products are water-based wet-based materials,
Normal moisture content is high, further drying is needed in the later stage, equipment investment
Large, long process, high energy consumption.
