用Mn改性Ru基催化剂并将其用于壬基酚加氢反应中，考察了助剂Mn对Ru/TiO₂催化活性的影响，并通过BET、XPS、NH₃-TPD、H₂-TPD、SEM表征手段分析了Mn的作用。结果表明，Mn的加入改变了Ru的电子特性，增强了吸氢能力和酸性中心数，提高了催化活性。在反应温度为180℃、反应压力为4 MPa、反应时间为6 h的最佳工艺条件下，反应转化率为99.53%，选择性为99.73%。催化剂重复使用5次活性未降低，具有较好稳定性。

Ru-based catalyst is modified with Mn and used in the hydrogenation of nonylphenol.The action of Mn is characterized by BET,XPS,NH₃-TPD,H₂-TPD and SEM.Results show that the addition of Mn changes the electronic properties of Ru,enhances its absorption capacity to hydrogen,increases the number of acid sites,and improves the catalytic activity.The optimum conditions for the hydrogenation of nonylphenol are as follows:reaction temperature is set at 180℃,reaction pressure is 4 MPa and reaction time is 6 h.The reaction conversion rate can reach 99.53% and the reaction selectivity can achieve 99.73% under the optimal conditions.Furthermore,the activity of the catalyst remains unchanged after 5 times of repeated use,representing a good stability.
