Abstract

Samples of Zn/H-ZSM-5 zeolite were prepared by impregnation of the parent zeolite with Zn(NO3)(2). The state of zinc in the samples was analyzed by XPS measurements, (ald the degree of reduction for the zinc oxide on the ZSM-5 zeolite surface in hydrogen atmosphere was determined, as well as the influence of this reducing treatment upon the activity and selectivity for aromatics of zeolites in aromatization of cyclohexane. It resulted that the degree of reduction depends on the concentration of zinc in the zeolite and is influenced by the presence of alumina binder. The results of the activity and selectivity to aromatics were correlated with the reduction of zinc oxide.
