Activated Alumina Carriers are used in the preparation of catalysts and their original purpose is to reduce the consumption of precious materials (such as Pd, Pt, Au).

Another goal is to use a stronger support to improve the abrasion and impact resistance of the catalyst.

 

Activated alumina has a large pore volume, specific surface area, and thermal stability, so it is widely used. One of the important properties of a catalyst carrier is the characteristics of its pore structure, and its pore structure determines the pore structure of the catalyst.

The requirement for the porous structure of the catalyst support is to provide the largest possible contact area for the reaction to improve the dispersion of the active components, followed by the pore size. 

Diffusion of ions has an adverse effect, thereby affecting the activity of the catalyst.

 

 

The active bimetallic components can be uniformly distributed on the surface of the alumina carrier to obtain a higher specific surface area, thereby improving the catalytic efficiency of the active components per unit mass.

Moreover, the activated alumina carrier enables the prepared supported catalyst to have suitable shape and mechanical strength to meet the operational requirements of industrial reactors.

Activated alumina carrier is a new kind of catalyst support and coating filler. It not only has the characteristics of high temperature, high pressure and high mechanical strength of an inert ceramic ball, but also has a certain catalytic activity. It can catalyze the processes of olefin saturation, desulfurization and denitrification.

 

For hydrotreating, hydrocracking, reforming prehydrogenation, and distillate oil benzene hydrogenation, an alumina active ball is filled at the top of the catalyst bed, and olefins in the secondary crude oil can be prehydrogenated. Reduced coking of the catalyst.

The use of activated alumina ball can not only effectively improve the space utilization of the reactor, but also protect the catalyst from poisoning and sintering to a certain extent, thereby extending the service life.

 

Character:

 

The pores of the activated alumina carrier are mainly formed by the accumulation of small particles, so the size and stacking method of the particles determine the pore structure and specific surface area of the carrier.
