Resumen:
The influence of the Ru/Sn ratio on the catalytic activity and selectivity of Ru-Sn-B catalysts for the hydrogenation of methyl oleate to oleyl alcohol was studied. The results show that the most active and selective catalyst for the formation of oleyl alcohol is Ru(1%)-Sn(2%)-B/Al2O3. When the amount of Sn is low (0.5%) the catalyst has high activity for hydrogenation of the C=C double bond and the C=O group. As a consequence, high amounts of stearyl alcohol are produced. At high Sn content (4%) the catalyst has lower selectivity to oleyl alcohol due to its low capacity to hydrogenate the C=O group. However it has enough activity for hydrogenating the C=C double bonds to produce the saturated methyl ester.
