摘要
采用浸渍法制备了不同载体负载钌催化剂,并考察其催化4,4’-二氨基二苯基甲烷(MDA)液相加氢制备反-反异构PACM性能,重点研究了第二金属助剂协同催化对催化剂综合性能的影响。结果表明,添加金属Re后催化剂活性、选择性均有明显提升,最优的Ru∶Re金属负载比例为5∶1,此时反-反异构体含量低于20%,且催化剂具有良好的稳定性。
The performance of ruthenium catalysts supported by different carriers based on impregnation method in liquid hydrogenation of 4,4’-diaminodicyclohexyl methane to trans-trans isomeric PACM was investigated,and the influence of the second metal additive on the performance of catalysts was studied.The results showed that the activity and selectivity of catalysts were significantly improved after the addition of metal Re,and the optimal loading ratio of Ru∶Re is 5∶1.The content of PACM trans-trans isomer is less than 20%.The catalyst has good stability.
