Pseudo Boehmite

Pseudo boehmite, a white gel (wet) or powder (dried), odorless, tasteless and nontoxic. It is thixotropic with the characteristics of high purity crystalline phase, excellent gelation and strong caking property.

It is also known as aluminum hydroxide gelatin, alumina monohydrate, false water boehmite. Its molecular formula AI2O3.H2O is produced by sodium aluminate solution and carbon dioxide gas as raw material, with a special glue technology process.

This series of aluminum hydroxide glue products with its stable high quality and excellent physical and chemical properties has been widely used in various petroleum distillate hydrogenation catalyst, coal tar hydrogenation catalyst, pyrolysis gasoline hydrogenation fine catalysts, a variety of chemical catalyst production.

Because of its lack of chloride and sulfur ions, this kind of aluminum hydroxide, used in the project is the first choice, especially in the various types of organic synthesis catalyst research and production.
