A durable Ni/La-Y catalyst for efficient hydrogenation of γ-valerolactone into pentanoic biofuels
文献摘要：
Zeolite-supported metal catalysts containing hydrogenation centers and acid sites are promising in the chemoselective hydrogenation of biomass platform molecules into value-added chemicals and fuels.The primary challenge of employing such bifunctional catalysts for biomass conversion lies in catalyst stability in the liquid phase under harsh conditions.Herein,we have prepared a Ni/La-Y nanocatalyst via an improved wet impregnation method.Compared with Ni nanoparticles on H-Y,La addition shows a significantly enhanced stability and performance in the continuous liquid-phase hydrogenation of γ-valerolactone(GVL)into ethyl pentanoate(EP)at 200℃for 1000 h.Complementary characterization studies reveal that La addition in the metal/zeolite catalyst not only efficiently modulates the acid prop-erty of the zeolite to alleviate coke formation,but also suppresses zeolite dealumination and metal agglomeration and leaching upon catalysis over a 1000 h period.These findings provide an efficient approach for improving the stability of zeolite-supported bifunctional catalysts,leading to potential application in hydrogen-assisted biomass valorization under the liquid-phase conditions.
