| titleOfInvention | Preparation method of self-supporting metal modified ZSM-5 molecular sieve and application thereof in synthesis of isoprene |
| abstract | The invention provides a preparation method of a self-supporting metal modified ZSM-5 molecular sieve, which comprises the following steps of firstly, dipping silica gel particles into a metal salt solution to obtain a precursor containing metal; and then mixing the metal-containing precursor obtained in the step with an alkaline template agent for forming the ZSM-5 molecular sieve, performing crystallization treatment, and roasting to obtain the self-supporting metal modified ZSM-5 molecular sieve. The invention directly compounds the active metal with silica gel, and then synthesizes and forms the molecular sieve, thereby realizing the one-step preparation of the self-supporting metal-ZSM-5 zeolite molecular sieve catalyst, avoiding the complex procedure of the later forming of the catalyst, having simple preparation method process, reducing the preparation cost of the catalyst, having better raw material conversion rate and product yield in the reaction of synthesizing isoprene, and being beneficial to the industrialized production and the popularization and application of the metal-ZSM-5 zeolite molecular sieve catalyst. |
