| 英文摘要 | A series of iridium-rhenium catalysts with different impregnation sequences were prepared and the catalytic properties of these catalysts for glycerol hydrogenolysis were evaluated. the catalyst prepared by the impregnation of ir prior to re afforded the best selectivity to 1,3-propanediol of 49.2 % with 43.7 % glycerol conversion. these catalysts were also characterized by temperature programmed reduction (tpr), x-ray diffraction (xrd), transmission electron microscopy (tem), x-ray photoelectron spectroscopy (xps), nh3-temperature programmed desorption (nh3-tpd), fourier transform infrared spectroscopy (ft-ir) and h-2-chemisorption. it was found that ir-0 species played a key role on the activities of glycerol conversion, and re species might act as an efficient promoter to improve the dispersive state of ir species as well as the reducibility. kinetic studies have also been conducted and it was observed that the number of ir-0 may affect the extent of consecutive hydrogenolysis of 1,3-propanediol over catalysts, and an appropriate number of ir-0 was of importance to 1,3-propanediol selectivity. |
