In this work the one-pot production of pentyl valerate(PV) from g-valerolactone (GVL) and pentanol in liquid phase at 523K, 10 bar of H2 over Ni-based catalysts supported on SiO2-Al2O3(SA) was studied. By using incipient wetness impregnation (I) andprecipitation-deposition (PD) two different catalysts were prepared,characterized and tested in reaction. With larger Ni0 particles anda significantly higher acid site density, Ni/SA-I was more active and selectiveto PV, revealing the crucial impact of preparation method on the catalyticperformance. After 24 h, a GVL conversion of 83.5% with PV selectivity of 87.8%was reached with Ni/SA-I.
