摘要：
The change in acidity of the ZSM-5 zeolite was investigated after it was treated with water vapour, and its capability on ammonia adsorption was also studied after having adsorbed water vapour. The effect of water vapour on products distribution was studied during catalytic cracking of naphtha, the changes in the adsorption ability and catalytic performance of the ZSM-5 zeolite was investigated after the catalyst was loaded with phosphorus species. These results all indicated that water vapour could reduce the acid strength and acid density of ZSM-5 zeolite and affect the capability of ZSM-5 on adsorption of gases, therefore the activated energy contributed by the ZSM-5 zeolite to the catalytic cracking reaction would be low to prevent the feedstock from deepened catalytic cracking and coke formation.
