摘　　要：本研究针对生物质糠醇的结构特点,以水相加氢性能优异的Ru催化剂为切入口,通过在催化剂制备工艺和活化条件、反应条件等方面的调控,探索生物质糠醇的直接氢解联产四氢糠醇和1,2-戊二醇的高效催化体系。研究发现,以碱性金属氧化物为载体制备Ru基催化剂可以提高产物中1,2-戊二醇的收率和选择性,其中,Ru/MnO_(2)在最佳反应条件下最高可以得到四氢糠醇(53%)和1,2-戊二醇(32%)总收率85%。实验结合了N_(2)吸附-脱附、XRD、XPS等表征手段对反应前后催化剂进行分析,并发现反应中催化剂表面会产生碱性基团与活性金属产生协同催化促进反应进行。In this paper,Ru/solid base catalysts were employed to realize the direct hydrogenolysis of furfuryl alcohol into tetrahydrofurfuryl alcohol and 1,2-pentanediol.Moreover,the catalyst preparation,activation and reaction conditions were screened.It was found that the yield and selectivity of 1,2-pentanediol were improved by the preparation of Ru based catalyst with basic metal oxides as support.The total yield of tetrahydrofurfuryl alcohol(53%)and 1,2-pentanediol(32%)was 85%under the optimal reaction conditions over Ru/MnO_(2).Subsequently,N_(2) adsorption-desorption,XRD and XPS were employed to reveal the catalytic mechanism which suggested that the synergistic between the surface basic groups and active metals might account for the better catalytic performance.
