Pseudo-Boehmite
1. Product characteristics
This products are non-toxic, odorless, white colloid (wet) or powder (dry), high purity crystal phase, good peptization performance, strong adhesion, and characteristic of thixotropic gel.
2. Product applications
Ordinary drying and drying pulverization products are mainly used in catalytic cracking catalysts, hydrogenation catalyst carriers, and tail gas treatment catalysts. Low-sodium pseudo-boehmite can be used as a binder for synthesizing rare-earth Y-type molecular sieve cracking catalyst, binder for aluminum silicate refractory fiber, alcohol dehydration to ethylene catalyst and ethylene oxide catalyst, and can also be used as raw materials for activated alumina and other aluminum salts.
3. Product specifications
The products implement the standard of Chalco Q/CHALCO A020—2012.
