摘要：

Hydrogenolysis of biomass-derived glycerol is an alternative route to produce 1, 2-propanediol. Supported Cu catalysts were prepared by the wetness impregnation method and characterized by N-2 adsorption-desorption, X-ray powder diffraction (XRD), X-ray photoelectron spectroscopy (XPS), Fourier transformed infrared spectroscopy (FT-IR), temperature programmed desorption of NH3 (NH3-TPD) and temperature programmed reduction (TPR) techniques, and then tested for glycerol hydrogenolysis. It was found that the nature of support significantly affected the performance of the catalysts, revealing a correlation between catalytic activity and total acidity. Compared with ZrO2, SiO2 and HZSM-5, gamma-Al2O3 showed superior performance due to its surface properties, and with 20wt% Cu loaded, glycerol conversion and 1, 2-propanediol selectivity reached 85.05% and 85.71% at 513 K and 6 M Pa H-2, respectively.
