“…Copper can be supported on a wide fan of metal oxide supports with different properties. A Cu/MgO prepared with a metal-organic chemical vapor deposition method achieved a C = 91% and S = 94% at 100 bar of H 2 for 10 h [146]. The loading of copper was found to be crucial for the catalytic activity and selectivity towards 1,4-PDO.…”

Levulinic acid and its esters are close to being extensively produced through consolidated industrial processes, thus playing a central role in biobased industries producing commodities within the principles of the circular economy. One of the main pathways of levulinic acid and ester valorization is their transformation with hydrogen to obtain γ-valerolactone, valeric esters, 1,4-pentanediol and 2-methyl tetrahydrofuran. These reactions are catalyzed by noble and non-noble metal-based heterogeneous catalysts. The use of an abundant and non-toxic element, such as copper, is advantageous with respect to expensive or harmful metals, such as Rh, Ru, Pt or Ni. In this critical review, we wish to give a deeper insight into research advancements in the last ten years regarding the processing of levulinic acid and its esters with hydrogen using heterogeneous copper catalysts.

“…Moving from 6 to 18 copper wt.% loading, conversion increased from 71% to 80%, reaching the maximum selectivity of 86%. On the other hand, when the copper loading was further increased, a rise in selectivity for 2-MTHF and 1-pentanol was observed [146].…”

“…The majority of recent research has been concentrated on Cu-based catalysts. Zhai et al employed a Cu/MgO catalyst with a 9% Cu concentration composed through metalorganic chemical vapour deposition (MO-CVD) on a MgO support, which achieved a 64% yield of PDO at 240 • C in dioxane solvent and at 80 bar H 2 [29]. Furthermore, it was discovered that the numerous basic sites of CuMg catalysts, through Cu minimal concentration, are required for the ring-opening/breaking of the furan ring in GVL to generate PDO [30].…”

2-Methyltetrahydrofuran (MTHF) is a desirable biomass-based platform chemical with excellent potential as an ideal biofuel, green solvent, and raw material for synthesizing downstream chemicals. In this work, a series of copper nanoparticles encapsulated on SiO2 were prepared by the wet impregnation method and evaluated as efficient non-noble metal catalysts for the vapour-phase hydrogenation of γ-valerolactone (GVL) to MTHF in a fixed-bed reactor under mild reaction conditions. The obtained catalyst properties were determined by XRD, FE-SEM, TEM, UV-DRS, TPR, NH3-TPD, N2O decomposition and pore size distribution measurements. Meanwhile, the parameters/variables tuning their catalytic performance (activity, conversion, selectivity and stability) were examined. Various Cu loadings featured on the SiO2 support are essential for tuning the catalytic activity. Among the catalysts tested, a 5 wt% Cu/SiO2 catalyst showed a 97.2% MTHF selectivity with 71.9% GVL conversion, and showed a stability for 33 h time-on-stream, achieved at 260 °C and atmospheric pressure conditions. It was found that a huge dispersion of Cu metal in support, hydrogen activation ability, abundant acidic sites and surface area are all beneficial for improved MTHF selectivity.
