摘要：

In this work, the effect of the preparation method (sol-gel vs. impregnation) over conversion and selectivity to oleyl alcohol in the hydrogenation of methyl oleate over Ru-Sn/Al2O3 catalysts at 270°C and 5 MPa was evaluated. The catalysts were characterized by SEM-EDS, TPR, XRD and surface area by nitrogen adsorption. The sol-gel method produced high dispersion of metals in the support, however catalysts prepared by sol-gel method were less reducible. For both methods an optimum Sn/Ru atomic ratio that allowed higher percentage of unsaturated alcohol was found. For the impregnation method this atomic ratio was 2 and for sol-gel method was 1. However, higher conversions and higher selectivity toward the oleyl alcohol were obtained with the impregnation method, using the optimum atomic ratio.
