SB-Powder (Sasol Boehmite) is a kind of high-quality high purity quasi boehmite produced from high purity aluminum and high alcohol. It’s used in Catalysts. Due to its good crystal shape, easy-to-control pore structure, large specific surface area, and high purity, it is widely used in the field of catalysts. It is reflected in the following two aspects:
- Used as a catalyst binder in the petrochemical industry
The pseudo-boehmite after acid dissolution has adhesive properties and is one of the main components of the double aluminum base binder for FCC catalyst. As a binder, pseudo-boehmite can not only improve the strength of the catalyst, but also adjust the pore size distribution of the catalyst, improve the hydrothermal stability of the catalyst, adjust the density of the acid active center of the catalyst, and improve the catalytic activity.
- Used as catalyst or catalyst support
Boehmite is widely used as catalyst support for chemical, oil refining, and petrochemical reactions. Typical examples include hydro refining catalyst support, reforming catalyst support, methanation catalyst support, etc. Pseudo-boite can also be used as a catalyst after dehydration. γ-alumina obtained after low-temperature roasting is used as Claus sulfur recovery catalyst, ethanol isomerization catalyst, and ethanol dehydration catalyst.
- In contrast, in the domestic sodium aluminate solution carbonation method, the production of low-grade products, in the field of catalyst application is limited, generally only used for the synthesis of raw material purity, and the structure of the catalyst is not high, such as hydrothermal synthesis of molecular sieve production.
