Activated Alumina For Petrochemical
1.Activated alumina for petrochemical as catalyst carrier
2.Characteristics:a porous structure, high specific surface area and in an unstable transition state
3.It can not only promote the effective dispersion of active components, but also facilitate the migration of raw materials
Product Introduction
Product Introduction
Activated alumina powder can be calcined at 1050 °C to obtain γ-phase kind, which can be made into an activated carrier through a molding process. The activated Al2O3 powder molding process has an influence on the physical structure of the catalyst, but the degree of influence depends on the molding method.
The active component loading process will lead to a slight decrease in the surface area, pore volume, pore size and particle mechanical strength of the activated alumina for petrochemical.
The performance of the catalyst in the reaction is directly related to the physical structure. The larger specific surface area, pore size and pore volume of the it are conducive to the dispersion of active components, thereby improving the propane conversion rate, propylene selectivity and stability of the catalyst, while inhibiting the formation of carbon deposition species.
When the calcination temperature of it is increased, the sintering effect is continuously enhanced, and the particles of the activated alumina catalyst carrier continue to grow, which is conducive to a more concentrated pore volume distribution.

Characters:
When AVANT calcined the activated alumina for petrochemical the converter calcined carrier had a large surface area, a low pore volume distribution ratio with a pore size of 2-6 nm, and a high pore volume distribution ratio with a large pore size of 6-20 nm.
Activated alumina catalyst carrier produced by AVANT have larger surface area, pore volume and average pore size, showing better catalytic performance.
Activated alumina for petrochemical as catalyst carrier can not only promote the effective dispersion of active components, but also facilitate the migration of raw materials, reaction intermediate species and target products.
