Pseudo-boehmite

 

1. Product performance:
Pseudo-boehmite, also known as aluminum hydroxide gel and alumina monohydrate. The molecular formula is Al2O3•H2O (1.2~2.2), with the performance of non-toxic, odorless, powder (dry), high purity of crystal phase , good peptization performance and strong adhesion. According to different production processes, different products can be used for different applications. Using high purity aluminum hydroxide and ion-exchange membrane alkali as the basic raw materials, after carbonation, it adopts different processes to produce a series of large-pored pseudo-boehmite products. This series of products have very stable quality and excellent physical and chemical properties

2.Application:
This series of products have been widely used in petroleum distillate hydrogenation catalysts, cracking (gasoline hydrotreating) catalysts and chemical catalysts.
