| titleOfInvention | Synthesis method of ZSM-22 molecular sieve and ZSM-22 molecular sieve synthesized |
| abstract | The invention relates to a method for synthesizing a ZSM-22 molecular sieve and the synthesized ZSM-22 molecular sieve, and mainly solves the problems in the prior art that the thickness of ZSM-22 molecular sieve nanosheets exceeds 20 nanometers, and there is no diffusion advantage compared with conventional rod-shaped ZSM-22 molecular sieves. At the same time, the synthesis steps are cumbersome and not suitable for the problem of industrial scale-up production. The present invention adopts the steps of crystallizing and calcining the mixture formed by silicon source, aluminum source, alkali source, templating agent and water to obtain ZSM-22 molecular sieve; wherein, the alkali source does not contain K + ; in the mixture , the molar ratio of the silicon source in terms of SiO 2 , the aluminum source in terms of Al 2 O 3 , the alkali source in terms of OH , the template agent and water is 1:(0.001～0.05):(0.001～0.3):( 0.04～0.4): (5～30), and the technical scheme that the molar ratio of Na + and template agent is (0.15～1.5): 1 solves the problem well, and can be used in the industrial production of ZSM-22 molecular sieves . |
