| 摘 要： | 对镍系SBS催化加氢机理进行了探讨,对催化剂制备工艺进行了优化。当催化剂组分质量浓度为2～4 g/L,陈化温度为50～70℃,n(Al)/n(Ni)为3～6时催化剂活性最高。向待加氢胶液中加入一定量破杂剂A可使催化剂活性及稳定性有一定程度提高。用该法制备的催化剂有较好的稳定性,常温下放置一个月其催化活性几乎没有变化。

| Abstract: | The hydrogenation reaction mechanism of SBS with nickel catalyst was discussed.The preparation of hydrogenation catalyst has been optimized.The catalyst has highest activity when the concentration of catalyst components is the 2～4g/L,aging temperature is 50～70℃,Al/Ni molar ratio is 3～6.The activity and stability of catalyst can be improved when add a certain amount of metallorganic compound A to SBS solution.This catalyst has good stability,its activity did not change when placed one month at room temperature. |
