| titleOfInvention | A method for ultrasonic-assisted synthesis of hierarchical porous SAPO-34 molecular sieves |
| abstract | The invention provides a method for ultrasonic-assisted synthesis of hierarchical porous SAPO-34 molecular sieves, comprising the following steps: adding a certain amount of deionized water, an aluminum source, a phosphorus source, a silicon source, a template agent, and an acidic solution according to a certain ratio, Sequentially mixed and stirred, and after aging for a certain period of time, the aging solution was subjected to ultrasonic treatment for a certain period of time. The aging liquid prepared above is subjected to crystallization treatment, followed by washing, drying and roasting to prepare a multi-level porous SAPO-34 molecular sieve catalyst. The multi-level pore SAPO-34 molecular sieve prepared by the invention has uniform particle size distribution and short crystallization time, and has the advantages of complex multi-level pore structure, and the surface of the molecular sieve presents an hourglass-like shape; 535m2/g. The hierarchical porous structure helps to provide more active sites for the reactant molecules, and the reaction product diffuses out of the molecular sieve faster; at the same time, the B acid and L acid centers and acid amounts on the surface of the molecular sieve are changed compared with the original molecular sieve. |
