摘要：

Ni3Al-N-R and Ni3Al-C-R catalysts with Ni/Al mole ratio of 3:1 were prepared by using NO3- and CO32- intercalated hydrotalcites as precursors respectively, and their catalytic properties for the hydrogenation of levulinic acid were investigated. The precursors and catalysts were characterized by N2-physical adsorption, ICP-OES, TG/DTG, XRD, H2-TPR / TPD, TEM, NH3-TPD, in-situ Py-FTIR and other characterization methods. The results showed that the intercalation anions played an important effect on the active metal-support interaction, active metal dispersion, surface acid properties, and catalytic performance of catalysts for levulinic acid hydrogenation. The catalyst derived from CO32- intercalated hydrotalcite exhibited high metal dispersion, rich L acid acidic centers, high C=O hydrogenation activity, and high recycle stability. When methanol was used as the solvent at 160℃ and 4 MPa hydrogen pressure for 1 h, the yield of γ-valerolactone could reach 71.8%. © 2020, Chemical Industry Press Co., Ltd. All right reserved.
