| titleOfInvention | Method for improving stability of ZSM-5 zeolite catalyst for preparing phenylacetaldehyde by rearrangement of styrene oxide |
| abstract | The invention relates to a method for improving the stability of a ZSM-5 zeolite catalyst for preparing phenylacetaldehyde by rearrangement of styrene oxide, belonging to the field of fine chemical catalysis. Firstly, carrying out alkali solution treatment on a ZSM-5 zeolite catalyst, and then loading a certain amount of phosphorus or boron by an impregnation method to respectively adjust the pore channel structure and the acidity of the zeolite. Wherein, the mesoporous structure can be introduced into the zeolite structure by alkali treatment, the acid strength of the strong acid sites of the zeolite can be reduced by loading phosphorus or boron, the diffusion rate of molecules is accelerated in the catalytic reaction process, the occurrence probability of side reactions and the formation of carbon deposit are reduced, the stability of the catalyst is improved by 8-10 times, and obvious inactivation is not seen after continuous operation for 100 hours. |
