摘要：

Investigating alternative energy sources is now crucial since the topic of climate action is growing in significance. One of the most promising renewable biomass feedstocks is levulinic acid (LA), which can be converted via an intermediary called gamma-valerolactone (GVL) into value-added products. This study examined the hydrogenation of levulinic acid to gamma-valerolactone using various copper-supported H-ZSM-5 catalysts with different Cu loadings (2-30 wt%) that were synthesized using a simple impregnation technique. The synthesized catalyst's morphological and chemical structure was examined using a variety of techniques, including XRD, N2 adsorption-desorption, TPR, TPD-NH3, and N2O titration. Overall, at 265 degrees C and 30 hours of time on stream (TOS), 5 Cu/H-ZSM-5 showed the best conversion (87%) and selectivity (83%).Graphical AbstractOne of the most promising renewable biomass feedstocks is levulinic acid (LA), which can be converted via an intermediary called gamma-valerolactone (GVL) into value-added products.
