Resumen:
The influence of the operating conditions and preparation methods of
RuSnB/Al2O3 catalysts on the activity and selectivity for the hydrogenation of
methyl oleate to oleyl alcohol was studied. It was found that catalysts prepared by
incipient wetness (IW) are more active and selective than those prepared by
co-impregnation. This better performance is possibly due to a lower level of residual
chlorine. The experiences of hydrogenation of methyl oleate showed that activity
increases as the reaction temperature increases while the selectivity to oleyl alcohol
has a maximum value. This could be due to the higher activation energies for the
hydrogenolysis of carboxymethyl groups than those found for C=C double bonds
hydrogenation. The increase in operating pressure has a positive effect on the
activity but it influences selectivity time patterns in a more complex way. Experiments
carried out by varying methyl oleate/n-dodecane ratio show that the selectivity
and conversion not depend on this parameter. A simple kinetic model is
proposed.
