제목 | Direct Hydrocyclization of Biomass-Derived Levulinic Acid to 2-Methyltetrahydrofuran over Nanocomposite Copper/Silica Catalysts |
초록 | Nanocomposite Cu/SiO2 catalysts, which were prepared by a precipitation-deposition method, are effective for the hydrocyclization of biomass-derived carboxylic acids such as LA, SA, and FA to the corresponding cyclic hydrofurans or cyclic lactones in vapor phase reactions at moderate H2 pressures. In the reaction of LA, the Cu/SiO2 catalysts shows increased selectivity for MTHF with increasing the copper loading up to 80 wt%. The addition of nickel to the catalyst with a high copper loading shows the effect of the promoter, through the enhanced selectivity. The nanocomposite catalysts can be used for long-term reactions without remarkable sintering and leaching of copper, and so could be promising candidates for hydrocyclization or hydrogenation in biorefinery research. |
