Zn对苯选择加氢制环己烯Ru催化剂性能的影响
Influence of Zn on Property of Ru Catalyst for Selective Hydrogenation of Benzene to Cyclohexene
摘要
Abstract
A Ru-Zn catalyst for selective hydrogenation of benzene to cyclohexene is prepared by co-precipitation of ruthenium trichloride and zinc sulfate with NaOH, followed by hydrogenation reduction in its aqueous mother liquid. The pronounced positive effect of zinc additive on the conversion of benzene and the cyclohexene selectivity and yield are investigated. Cyclohexene yield achieves 49.1 % (molar fraction) at 15 min as x(Zn)/x(Ru) ratio is 0.08.XRD and H2-TPR are also carried out to obtain better insight into the structure of the catalyst. The results show that ruthenium and zinc form a solid solution and zinc exists in its metal state in the catalyst with lower content of zinc, and while the content of zinc increases further, a new phase of zinc is found.关键词
