Pseudo-boehmite: also known as monohydrated alumina, pseudo-monohydrate soft stone. Its series include: pure aluminum hydroxide powder, silicon-aluminum composite aluminum hydroxide powder, silica-aluminum colloid, active magnesium aluminum spinel precursor, alumina special-shaped carrier series, macroporous pseudo-boehmite, low-sodium pseudo-boehmite.
Shandong Bairui Chemical Macroporous Pseudo-boehmite is white colloid in wet form and white powder in dry form, with uniform pore size distribution, large volume and good water absorption. It has high radial purity, good molding performance and the characteristics of thixotropic gel. This product has good dispersibility, is easily soluble in strong acid and strong alkali solutions, has good molding performance, and becomes highly active alumina after low-temperature roasting and dehydration.

Main uses: This product is mainly used as a catalyst carrier - raw material for activated alumina, such as a raw material for hydrogenation catalysts and for the manufacture of hydrogenation catalyst carriers, oxychlorination catalyst carriers, etc. It can also be used as a molding binder for molecular sieves and silicate refractory fiber products, such as a binder for semi-synthetic rare earth Y-type molecular sieve cracking catalysts. This product is a good raw material for various aluminum salts. After molding, it can be used as a desiccant, adsorbent and catalyst carrier in different shapes.
Packaging and storage: Pseudo-boehmite is packaged in woven bags. It can be packaged according to customer requirements. Store in a cool, ventilated and dry warehouse.
