| titleOfInvention | Preparation method of binder-free ZSM-5 molecular sieve |
| abstract | The invention relates to a preparation method of a binderless ZSM-5 molecular sieve, which mainly solves the problems of long secondary crystallization time, incomplete crystallization and poor catalytic performance in the preparation process of the binderless ZSM-5 molecular sieve in the prior art. The invention adopts the following steps: a) providing a synthetic ZSM-5 molecular sieve; b) mixing the synthesized ZSM-5 molecular sieve with a binder, a pore-forming agent and an aqueous solution of acid, forming and drying to obtain a ZSM-5 molecular sieve precursor; the binder is selected from at least one of silica sol or alumina; wherein the silica sol provides a first silicon source, and the alumina provides a first aluminum source; c) crystallizing a mixture of the ZSM-5 molecular sieve precursor, a second silicon source, a second aluminum source, an alkali source, an organic template and water, and separating and drying a solid product to obtain the binderless ZSM-5 molecular sieve; controlling the total Si/Al molar ratio SiO in the first Si source, the second Si source, the first Al source and the second Al source 2 /Al 2 O 3 The technical scheme of 25-100 better solves the problem and can be used for industrial production of the binder-free ZSM-5 molecular sieve. |
