Bimetallic Ni-Zn@OMC catalyst for selective hydrogenation of levulinic acid to γ-valerolactone in water

Recent Advances in Lignocellulose-Based Monomers and Their Polymerization

“…Xu et al obtained a from-5-HMF-to-maleic anhydride yield of 52% using VO(acac) 2 as a catalyst after a reaction at 90 °C for 4 h in acetonitrile through the simultaneous oxidation of hydroxymethyl group and C–C bond cleavage of 5-HMF [ 27 ]. Levulinic acid is an important biomass-derived platform chemical as an intermediate for the preparation of polymer monomers such as succinic acid [ 28 , 29 , 30 ]. The acid-catalyzed decomposition of 5-HMF for the preparation of levulinic acid has been widely reported, but most of them were limited by low yields and deficient economic efficiency.…”

Regulation of Pt Loading on Co/Al2O3 Catalysts for Selective Hydrogenation and Hydrogenolysis of 5‐Hydroxymethylfurfural to 2,5‐Bis(hydroxymethyl)furan and 2,5‐Dimethylfuran

“…Newly, the thermochemical conversion of platform substances derived from lignocellulosic biomass such as furfural (FAL), 5-hydroxymethylfurfural (HMF), and levulinic acid (LA) though the hydrogenation and hydrogenolysis reactions under pressurized H 2 system have been widely investigated using heterogenous catalysts. [1][2][3][4][5][6][7] Among the platform substances, the HMF derived from cellulose fraction via hydrolysis and dehydration processes could be utilized as a useful feedstock for the production of biofuels and biochemicals based on the modern biorefinery concept. In thermochemical routes under H 2 atmosphere, the valuable multipurpose compounds of 2,5-bis(hydroxymethyl)furan (BHMF) 2,5-dimethyltetrahydrofuran (DMTHF) 5-methylfurfuryl alcohol (MFA), 5-methylfurfural (MF), and 2,5-dimethylfuran (DMF) could be generated from the hydrogenation of C=O bond and hydrogenolysis of CÀ OH bond of HMF using heterogenous non-noble and noble catalysts.…”

Highly efficient Ni–Mn/SiO2catalyst for the selective hydrogenation of biomass-derived levulinic acid to γ-valerolactone under mild conditions

“…Compared with noble metals, the selective hydrogenation of LA to GVL over non-noble metals such as Ni, Cu and Co is promising and challenging. 14–16 In particular, Ni shows the highest activity due to its strong hydrogen activation ability as well as its strong tendency to break the C–O bond compared with other non-noble metals. 17 Unfortunately, monometallic Ni catalysts usually show low activity and selectivity to GVL.…”
