Shandong Bairui pseudo-boehmite is odorless. Pseudo-boehmite is white colloidal (wet product) or powdery (dry product), with high crystal purity, good molding performance, and the characteristics of thixotropic gel.
Uses:
This product is mainly used as a raw material for catalyst carriers - activated alumina, and 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, as alcohol dehydration catalysts for ethylene and ethylene oxide catalysts, etc.
