The catalytic performance of Pt, PtSn and PtGe supported on ãAl2O3 (ãA) deposited by dip coating of spheres of áAl2O3 (áA) is studied in the ndecane dehydrogenation. The effect of Sn and Ge addition to Pt on the activity and selectivity was analyzed. The catalytic characterization was carried out by using cyclohexane dehydrogenation (CHD), cyclopentane hydrogenolysis (CPH), temperaturepro grammed reduction (TPR), hydrogen chemisorption, Xray photoelectron spectroscopy (XPS), thermo gravimetric analysis (TGA) and scanning electronic microscopy (SEM). Pt(0.5)Sn/ãA/áA catalyst had the best catalytic performance and showed a low electronic interaction between the metals, with a surface segre gation of Sn and the presence of oxidized Sn stabilized on the support. PtGe catalysts presented strong inter actions with probable alloy formation. The catalytic performance of these catalysts is comparable to that reported in the patents. best catalytic performance and showed a low electronic interaction between the metals, with a surface segre gation of Sn and the presence of oxidized Sn stabilized on the support.
