| 摘 要： | 通过后修饰法制备出高分散的金属纳米催化剂Au/SBA-15,并运用XRD对制备的催化剂进行表征。以糠醛加氢制糠醇的反应为例,考察反应温度、反应压力及反应时间等对催化剂催化性能的影响。结果表明,含金质量分数为1%、反应温度220℃、反应压力5MPa、反应时间4h、催化剂质量分数2%的条件下,糠醛的转化率为92.1%,选择性97.8%。经过6次重复实验,催化剂的性能没有明显下降。

| Abstract: | Highly dispersed nanosized Au supported on SBA-15 by post-synthesis method was prepared and characterized by XRD techniques,and its catalytic performance on selective hydrogenation of furfural to furfuryl alcohol was evaluated.The effect of reaction temperature,reaction pressure and reaction time on its catalytic performance was investigated,and find the optimum conditions are as follows: mass fraction of Au 1%,reaction temperature 220 ℃,reaction time 4 h,reaction pressure 5 MPa,mass fraction of catalyst 2%.The conversion of furfural and the selectivity to furfuryl alcohol are 92.1% and 97.8%,respectively.The catalyst can be recycled,and there is no obvious decrease on catalytic performance after 6 cycles. |
