Four Types Of Pseudo-boehmite Are Introduced

We all know pseudo-boehmite, non-toxic, tasteless, odorless, is a kind of white colloid (wet) or powder (dry), high crystal purity, strong adhesion, high chemical properties of specific surface area, so pseudo-boehmite is also more widely used, used for oxy ethane catalyst, catalyst carrier, activated alumina, aluminum salt, etc. In addition, it is also the main raw material of phosphorus aluminum molecular sieve and phosphorus aluminum molecular sieve. Today, we introduce the four types of pseudo-boehmite, so that you can have a clearer understanding of pseudo-boehmite. Let's understand it together

(1) general pseudo-boehmite

This kind of pseudo-boehmite requires high crystal purity, good colloidal property and strong adhesion. It can be used as half component rare earth Y molecular sieve cracking catalyst binder, aluminum silicate refractory fiber binder, alcohol dehydration to ethylene catalyst and ethylene oxide catalyst.

(2) special pseudo-boehmite

This kind of pseudo-boehmite requires high crystal purity and good molding performance. γ-Al2O3 is mainly prepared as catalyst carrier for catalytic hydrogenation in petroleum refining.

(3) lightweight aluminum adhesive

It requires good formability, good adhesion, small bulk density and low sulfur content. Catalysts used in the production industry as methanation catalyst and organic tail gas incineration catalyst materials, as well as various aluminum salt materials.

(4) aluminum silica gel

The pseudo-boehite has a low volume density, large specific surface area and pore volume, and low sulfur content, with SiO2 content ranging from 26% to 31%. The product can be used as the adsorption and raw material of hydrocracking catalyst, and can be used in hydrotreating.
