Characteristics of pseudo boehmite:
Pseudoboehmite is a non-toxic, tasteless and odorless white colloidal (wet) or powdery (dry) product with small particle size, high pore volume, large specific surface area, good gel solubility, high crystal phase purity, and thixotropic gel characteristics. It is very easy to dissolve in strong acids and alkalis, and the dry powder has moisture absorption when exposed to the air.
The main application forms of pseudo boehmite:
Aluminum source used as a binder and molecular sieve synthesis in the petrochemical and refining catalyst industries
Pseudo boehmite is mainly used as a catalytic cracking catalyst and binder. Pseudo boehmite as a binder can not only improve the strength of the catalyst, but also adjust the pore size distribution of the catalyst, improve the thermal and hydrothermal stability of the catalyst, adjust the density of the acidic active center of the catalyst, and improve catalytic activity.
2. Used as a catalyst carrier
Pseudo boehmite is widely used as a catalyst carrier for various reactions in chemical, oil refining, and petrochemical industries. Its typical examples include hydrofining catalyst carriers, reforming catalyst carriers, methanation catalyst carriers, etc. After dehydration, pseudo boehmite becomes γ- Aluminum oxide can also be used as a catalyst.
