摘要：

The influence of the chlorine content on the Pt-Re interaction and the modification of the catalytic properties of reforming catalysts prepared by co-impregnation were studied. Chlorine inhibits Pt-Re interaction and produces a decrease in the deposition of coke over the metallic function. In monometallic Pt catalysts, chlorine produces lower coke deposits, but its toxicity in cyclohexane dehydrogenation is the same and the catalytic activity is independent of chlorine content. For bimetallic catalysts, the greater the Pt-Re interaction, the lower the deactivation by coking of the metallic function.
