中文摘要:
      采用等体积浸渍法制备了不同载体的钌催化剂,考察系列催化剂在邻苯二甲酸二异壬酯加氢制备1,2-环己烷二甲酸二异壬酯中的催化性能,Ru/Al2O3表现出优异的催化性能,并对载体Al2O3进行改性,确定最佳的改性条件为140℃水热4h,造孔剂添加量为1%,黏合剂添加量为3%,700℃焙烧4h。改性后的Al2O3载体负载不同含量的钌,进行表征并评价催化活性,实验结果表明最佳的钌负载量为0.3%,在温度150℃、压力5MPa、空速0.25h-1的工艺条件下,邻苯二甲酸二异壬酯的转化率达到98.9%,1,2-环己烷二甲酸二异壬酯的选择性高达97.1%。
英文摘要:
      Ruthenium catalysts with different supports were prepared by equal volume impregnation method. Ru/Al2O3 was selected as the best catalyst for the hydrogenation of diisoononyl phthalate to diisoonyl 1,2-cyclohexane dicarboxylate. The support Al2O3 was modified by hydrothermal treatment at 140 ℃ for 4h, pore forming agent addition of 1%, binder addition of 5%, calcination at 700 ℃ for 4h. Al2O3 with different ruthenium loading amount was characterized and evaluated. The results showed that the best ruthenium loading amount was 0.3%. The conversion of diisoonyl phthalate was 98.9% and the selectivity of diisoonyl 1,2-cyclohexanedicarboxylate was 97.1% under the conditions of temperature 150 ℃, pressure 5MPa and space velocity 0.25h-1.
