| titleOfInvention | Preparation method of binderless Beta molecular sieve |
| abstract | The invention relates to a preparation method of a binderless Beta 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 Beta molecular sieve in the prior art. The invention adopts the following steps: a) providing a Beta molecular sieve in a synthetic state; b) mixing the synthetic Beta molecular sieve with a binder, a pore-forming agent and an aqueous solution of acid, forming and drying to obtain a Beta 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 Beta 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 Beta 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 20-100 better solves the problem and can be used in the industrial production of the binderless Beta molecular sieve. |
