Resumen:
In this work the one-pot production of pentyl valerate (PV) fromγ-valerolactone (GVL) and pentanol in liquidphase at 523 K, 10 bar of H2over Ni-based catalysts supported on SiO2-Al2O3(SA) was studied. By using in-cipient wetness impregnation (I) and precipitation-deposition (PD) two different catalysts were prepared,characterized and tested in reaction. With larger Ni0particles and a significantly higher acid site density, Ni/SA-Iwas more active and selective to PV, revealing the crucial impact of preparation method on the catalytic per-formance. After 24 h, a GVL conversion of 83.5% with PV selectivity of 87.8% was reached with Ni/SA-I.
