Abstract以不同硅铝比的HZSM-5为载体,采用化学还原法与沉淀法制备了负载型Ru /HZSM-5催化剂。通过XRD与TEM对催化剂进行了表征。系统考察了制备方法、硅铝摩尔比、温度、氢气压力、时间和Ru负载量对对苯二酚加氢的影响。由于化学还原法制备的催化剂中Ru粒径较小且分散均匀,得到了含有少量硼的非晶态钌硼合金,其催化性能明显优于沉淀法制备的Ru /HZSM-5催化剂。最佳优化反应条件为:硅铝摩尔比为740,反应时间为2.5 h,反应温度为140℃,氢气压力为2.5 MPa,Ru质量分数为1.0%,此时,对苯二酚转化率为100%,目标产物1,4-环己二醇选择性为90.13%。最后,对该催化体系下对苯二酚加氢的反应路径进行了分析。
