Description

Technical Field

[0001] The utility model relates to the technical field of pseudo-boehmite, and more specifically to a pseudo-boehmite carbonization device. Background Art

[0002] Pseudo-boehmite, also known as monohydrated alumina and pseudo-monohydrate soft boehmite, can be used as a binder for semi-synthetic rare earth Y-type molecular sieve cracking catalysts, a binder for aluminum silicate refractory fibers, a catalyst for alcohol dehydration to ethylene and a catalyst for ethylene oxide, etc. It can also be used as a raw material for the production of catalyst carriers, activated alumina and other aluminum salts.

[0003] There are many methods for producing pseudo-boehmite.

When producing pseudo-boehmite, the existing carbonization device directly introduces carbon dioxide gas into the reaction container, and the amount of carbon dioxide cannot be controlled. This will cause the pseudo-boehmite grains to be of different sizes, thereby reducing the final quality of the product, so it needs to be improved. Utility Model Content
