Introduction to SB powder and ultra-micro nano alternatives

SB (sasol boehmite) powder is a high quality and high purity pseudo-boehmite made of high purity aluminum and high alcohol as raw materials. It is widely used in catalyst field because of its good crystal shape, easy to control pore structure, large specific surface area and high purity. It is embodied in the following two aspects:

1. Used as a binder for catalysts in petrochemical industry

The acid-dissolved pseudo-boehite has adhesive properties and is one of the main components of the aluminum-based binders for FCC catalysts. Pseudo-boehmite as a binder can not only improve the strength of catalyst, but also adjust the pore size distribution of catalyst, improve the hydrothermal stability of catalyst, adjust the acid active center density of catalyst, and improve the catalytic activity.

2. Used as catalyst or catalyst carrier

Pseudo-boehmite is widely used in the production of chemical, oil refining and petrochemical reaction catalyst carrier, its typical examples such as hydrofining catalyst carrier, reforming catalyst carrier, methanation catalyst carrier and so on. Pseudo-bauxite can also be used as a catalyst after dehydration, and the γ-alumina obtained after low temperature roasting is used as Claus sulfur recovery catalyst, ethanol isomerization catalyst, ethanol dehydration catalyst, etc.

In contrast, the domestic sodium aluminate solution carbonation method is mainly used to produce middle and low grade products, and its application in the catalyst field is limited, and it is generally only used to synthesize catalysts with low purity and structure requirements of raw materials, such as hydrothermal synthesis method to produce molecular sieve.

An alternative to ultra-nano SB powder

Recently, the latest development of JWN high-purity series of Boehmite crystal phase purity, can be evenly dispersed in water, with less impurity content, good colloidability, strong adhesion, large specific surface area, moderate pore volume and other characteristics, performance and SB powder material, low price; JWN-3.5N-AH01 is obtained by aluminum isopropyl alcohol technology. It has the characteristics of 99.95% high purity, uniform particle size, large pore volume, large specific surface area, high viscosity and high colloidal index, and its performance is superior to that of SB powder.
