| 摘 要： | 采用分步浸渍和化学还原的方法制备以丝光沸石分子筛为载体的Ru-Sn-B催化剂，研究了在负载型催化剂Ru-Sn-B/丝光沸石上对苯二甲酸催化加氢制备1,4-环己烷二甲醇的加氢催化性能，并利用XRD和BET等分析手段对Ru-Sn-B/丝光沸石催化剂进行表征。结果表明，RuB和Sn在丝光沸石上具有较好的分散性，Ru-Sn-B/丝光沸石催化剂具有较高的催化活性和选择性；催化加氢过程中采用两段升温升压的方法，对苯二甲酸转化率约100%，产物1,4-环己烷二甲醇的收率为73.5%，反式与顺式之比为2.42

| Abstract: | Ru-Sn-B/mordenite catalysts were prepared by sequential impregnation and chemical reduction methods and using mordenite zeolite as the carrier.The catalytic performance of Ru-Sn-B/mordenite catalysts for terephthalic acid hydrogenation to 1,4-cyclohexanedimethanol was investigated.The as-prepared catalysts were characterized by XRD,BET,EDS and ICP.The results showed that RuB and Sn had better dispersion on the mordenite,and Ru-Sn-B/mordenite catalyst possessed high catalytic activity and selectivity.The catalytic hydrogenation process used two stage enhancement method of temperature and pressure.Terephthalic acid conversion rate of about 100%,the yield of the product 1,4-cyclohexanedimethanol of 73.5%,and the ratio of trans and cis of the product of 2.42 were attained,respectively. |
