INFLUENCE OF CHLORINE CONTENT ON PT-RE INTERACTION AND COKE DEPOSITION

The influence of the chlorine content on the Pt-Re interaction and the modification of the catalytic properties of reforming catalysts prepa red by co-impregnation were studied. Chlorine inhibits Pt-Re interacti on 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 bim etallic catalysts, the greater the Pt-Re interaction, the lower the de activation by coking of the metallic function.
