| titleOfInvention | Hierarchical Porous HZSM-5 Zeolite Molecular Sieve |
| abstract | The hierarchically porous HZSM-5 zeolite molecular sieve is prepared by the following method: first, the original powder of the ZSM-5 molecular sieve is calcined and then mixed and reacted with an alkali solution, and then mixed and reacted with an acid solution, and then a silicon source, an aluminum source and an organic alkali are added for the reaction. Hydrothermal synthesis, after separation, washing, drying, roasting, ion exchange with ammonium salt solution, and finally drying and roasting. The molecular sieve prepared by the invention has a regular MFI skeleton structure, and the secondary crystallization can generate a regular and controllable micro-medium hierarchical pore structure, and at the same time, a non-penetrating mesoporous structure is introduced to combine the microporous ZSM-5 molecular sieve with the molecular sieve. And the advantages of mesoporous materials, the macromolecules generated in the process of biomass catalytic thermal cracking can easily enter and stay in the active site of the molecular sieve, shorten the diffusion path, reduce the diffusion resistance of reactant molecules and product molecules in the pores, and improve the The probability of contact between reactant molecules and active sites, thereby increasing aromatic carbon yield and reducing coke formation. |
