The selectivity and deactivation by coke of Pt-Re-S/A1203-C1 catalysts with different chlorine content were studied in the reforming of commercial naphtha cuts and cuts prepared by doping a typical naphtha for reforming with n- paraffins and isomer fractions. Runs at simulated industrial conditions with periods of accelerated deactivation were carried out. The results were obtained by chromatographic analysis of the gaseous effluent and were compared with the cut composition (mainly paraffins distribution). Cuts with a higher content of n-paraffins than isomers with the same number of carbon atoms give higher aromatics formation and lower production of gases than a naphtha rich in isomers.
