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 in different forms, such as spheres, columns, strips, and granules. Manufacturers can also adjust parameters such as pore volume, specific surface area, mechanical strength, and particle size according to the requirements of the final product. This is also an important reason why activated alumina powder can be used in the production of different types of catalyst supports.
1. Catalyst Supports for Petroleum Refining
Petroleum refining is one of the important application fields of alumina catalyst supports.
In processes such as hydrodesulfurization, hydrodenitrification, and hydrotreating, catalysts need to operate for long periods under relatively high temperatures, pressures, and complex chemical environments. Therefore, there are relatively high requirements for the stability, pore structure, and mechanical strength of the support.
Activated alumina powder can be used as a raw material for preparing alumina supports. Through forming and calcination, it can be made into supports suitable for loading active metal components.
For example, in some hydrotreating catalysts, the alumina support needs to have an appropriate pore structure so that active metals can be well dispersed on the surface and in the pores of the support. For this type of application, it is not appropriate to simply pursue a single parameter. Instead, suitable activated alumina powder needs to be selected according to the formulation and reaction conditions of the final catalyst.
2. Hydrodesulfurization and Hydrodenitrification Catalysts
These types of catalysts usually require specific metal active components to be loaded onto alumina supports. Therefore, the pore structure of the support will directly affect the dispersion of the active components and the contact efficiency after reactants enter the pores.
After processing, activated alumina powder can form alumina supports with appropriate pore volume and specific surface area to meet the requirements of different catalyst systems.
If the customer is producing a high-loading catalyst, particular attention needs to be paid to the pore volume and pore size distribution of the support. If greater attention is paid to the dispersion effect of active components, specific surface area, surface properties, and structural stability after forming need to be considered comprehensively.
3. Catalyst Supports for the Chemical Industry
In oxidation, hydrogenation, dehydrogenation, and other gas-solid catalytic reactions, alumina has good thermal stability and structural stability and can be used as a support for active components.
Different chemical reactions have very different requirements for supports. For example, some reactions require a larger specific surface area, some pay more attention to pore volume and pore size, and some high-temperature reactions place greater emphasis on the structural stability of the support during long-term operation. Therefore, even for activated alumina powder, different catalyst manufacturers may require completely different product specifications.
4. Catalysts for Industrial Gas Treatment
In the treatment of hydrogen, syngas, and other industrial gases, processes such as desulfurization, purification, and conversion are often involved. The related catalysts need to maintain stable performance under continuous operating conditions, so there are certain requirements for the structural stability and thermal stability of the support.
Activated alumina powder can be processed into supports with different shapes according to the requirements of the final catalyst, and the corresponding pore structure can be obtained by controlling the raw materials and forming processes.
If you are purchasing activated alumina powder for catalyst support production, you can first clarify the application of the final product.
For example, if it is used for petroleum refining catalysts, you need to focus on pore structure, specific surface area, thermal stability, and forming performance; if it is used for environmental catalysts, you need to make the selection according to specific reaction conditions and active components; if it is used for high-temperature catalytic processes, you need to pay greater attention to the structural stability of the material under high-temperature conditions.
