Activated Alumina Claus Catalyst for Petroleum Refining

Activated Alumina Claus Catalyst for  Petroleum Refining

Since its artificial synthesis, activated alumina supports have been widely used in automotive exhaust catalysts, petroleum refining catalysts, hydrodesulfurization catalysts and other fields. The utilization of catalyst in automobile exhaust purification is one of the important uses of catalyst.

There are great differences among various carriers. Al2O3 can be used as a carrier for CH4 autothermal reforming catalyst due to its suitable specific surface and pore structure, and the reactivity of different types of Al2O3 is also different.

Using Al2O3 as a carrier not only provides the contact surface between the reactant and the active center of the catalyst, but also Al2O3 interacts with the active component Ni to form a NiA12O4 spinel structure, which has a great impact on the activity of the catalytic reaction and carbon deposition.

Product advantage:

As the catalyst carrier,activated alumina has the following functions:

1. Increase the effective surface area and provide proper pore structure.

2. Improve the mechanical strength of the catalyst, such as abrasion resistance, hardness, compression strength and impact resistance;

3. Improve the thermal stability of the catalyst;

4. Save the number of active components and reduce costs.
