Zusammenfassung:The invention belongs to the technical field of chemical industry catalysts, and particularly relates to a nano ZSM-5/gamma-Al2O3 composite catalyst for preparing acraldehyde by glycerol dehydration, and a preparation method and application thereof. In the presence of nano ZSM-5, nano gamma-Al2O3 is prepared by a precipitation process, and the nano ZSM-5 and nano gamma-Al2O3 are uniformly mixed to obtain the composite catalyst with strong interaction. The nano ZSM-5/gamma-Al2O3 composite catalyst solves the problems of poor ZSM-5 stability and low gamma-Al2O3 selectivity in the acraldehyde catalytic reaction by glycerol dehydration. The prepared catalyst has excellent catalytic activity, selectivity and stability in the glycerol dehydration reaction.
