Resumen:
The influence of the kind of support (Al2O3, SiO2 and TiO2) on the catalytic activity andselectivity of Ru-Sn-B catalysts for the hydrogenation of methyl oleate to oleyl alcohol wasstudied. The results show that the most active and selective catalyst for producing oleylalcohol is Ru(1%)-Sn(2%)-B/Al2O3. This was attributed to the catalyst having a favorablesurface Sn/Ru ratio (≈2). The SiO2-supported Ru-Sn-B catalyst had a good activity andhydrogenated both C=C double bonds and the C=O group, thus producing stearyl alcohol witha high yield. It however deactivated to a great extent, its final conversion being lower thanthat of the bimetallic catalysts supported on Al2O3 and TiO2. The TiO2 supported catalyst hada high selectivity to saturated methyl esters because it hydrogenated C=C double bonds buthad little activity for hydrogenation of the C=O group.
