| titleOfInvention | Preparation method of nano hierarchical pore Beta molecular sieve |
| abstract | The invention provides a preparation method of a nanometer hierarchical pore Beta molecular sieve, belonging to the technical field of Beta molecular sieve preparation. Compared with the existing method for preparing the Beta molecular sieve by the steam-assisted xerogel conversion method, the method avoids the process of synthesizing the xerogel by evaporating the gel, and directly uses the solid-phase reaction mixture obtained by ball milling the raw materials such as tetraethylammonium bromide, solid silica gel and the like in the steam-assisted conversion, thereby simplifying the synthesis steps and reducing the synthesis cost; meanwhile, the migration and dispersion of solid phase raw materials are promoted due to the existence of steam, so that the nano hierarchical pore Beta molecular sieve which is small in nano particle size, dispersed and rich in intra-crystalline mesopores is prepared. |
