Activity and selectivity data obtained in n-hexane dehydrocyclization over Pt/Al2O3 and Pd-Pt/Al2O3 catalysts exposed to different thermal treatment processes are compared. The ageing phenomena were most pronounced on catalysts treated in hydrogen at higher temperatures. The Pd-Pt/Al2O3 catalyst possessed lower cracking activity with a parallel increase of the selectivity for benzene and iso-hexanes.
