The activities, selectivities and stabilities of bimetallic Pt-Re clusters supported on γ-alumina were evaluated in the n-hexane reforming reaction. Reaction temperature and calcination temperatures were varied at 300-500℃ and 400-500℃, respectively. Reduction was performed at 500℃. Pt-Re/alumina catalysts were prepared by coimpregnating the aqueous solution of H₂PtCl₆ and HReO₄. When the amount of Pt supported on alumina increased, the selectivity towards benzene increased, but the selectivity towards C₆ isomers decreased. Pt-Re/alumina was more active in the hydrogenolysis reaction at 400℃ than Pt/alumina, resulting in the higher selectivity towards C₁-C₅ com-pound. However, Pt-Re/alumina produced less C₁-C₅ compound and more benzene above 450℃ than Pt/alumina. The ativities and selectivities of Pt-Re/alumina were varied with different calcination temperatures, indicating that the for-mation of Pt-Re bimetallic cluster is dependent on the calcination temperature. The addition of Re on Pt improved the maintenance of activity by decreasing the deactivation rate.
