| titleOfInvention | Preparation method of metal modified hierarchical pore HZSM-5 molecular sieve |
| abstract | The invention relates to a preparation method of a metal modified hierarchical pore HZSM-5 molecular sieve, which comprises the following steps: 1) placing metal organic framework Materials (MOFs) in an inert gas atmosphere for roasting to prepare a metal-loaded porous carbon mesoporous template agent; 2) dissolving an aluminum source in a microporous structure directing agent, adding deionized water, stirring and dissolving at room temperature, and then adding a silicon source to obtain a molecular sieve precursor; 3) adding the porous carbon template agent obtained in the step 1) into a molecular sieve precursor for pre-crystallization; 4) after the pre-crystallization is finished, transferring the mixture into a hydrothermal kettle for hydrothermal crystallization; 5) and after crystallization is finished, centrifuging, washing, drying and roasting to obtain the metal modified hierarchical pore HZSM-5 molecular sieve. The HZSM-5 molecular sieve prepared by the method simultaneously introduces active metal and a multi-stage pore channel structure through a one-step method, and can simultaneously improve the catalytic activity and the stability of the molecular sieve. |
