High-purity Pseudo-boehmite
- Description
-
The pseudo boehmite adopts the alkoxide hydrolysis process, and the product purity is high (99.9%~99.999%). It can be used as a catalyst carrier, raw material for activated alumina, and also as a molding binder for molecular sieves and silicate refractory fiber products. For example, it can be used as a binder for semi synthetic rare earth Y-shaped molecular sieve cracking catalysts, as a catalyst for alcohol dehydration to produce ethylene, and as a catalyst for epoxy ethane. Suitable for industries such as coal chemical, petrochemical, fine chemical, pharmaceutical, pesticide, pigment, dye, environmental protection, and new energy.
