| Popis: | In this work, the influence of the pretreatment conditions (calcination and reduction temperature) on the activity and selectivity of Pt-Ir/TiO2 catalysts was studied. Two series of Pt-Ir/TiO2 catalysts with a constantamount of Pt (1.0 wt%) and different Ir contents (0.3, 1.0 and 2.0 wt%) activated at different temperatures were prepared. The catalysts were characterized by TPR and test reactions such as cyclopentane and methylcyclopentane hydrogenolysis and cyclohexane dehydrogenation. Theselective ring opening (SRO) performance of the catalysts was also evaluated on decalin. The catalysts activated by treatment at a lower temperature showed higher dehydrogenation and hydrogenolysis activity. Furthermore, they exhibited greater selectivity for ring opening products and reduced formation of dehydrogenated compounds. The activation treatment appears to be crucial, as its affects not only the activity, but the selectivity towards different reaction products. Fil: Vicerich, Maria Ana.
