| 摘 要： | 用共沉淀法制备了纳米Ru-Zn催化剂,考察了阿拉伯树胶修饰对苯选择加氢制环己烯催化剂性能的影响,并用X射线衍射(XRD)、透射电镜(TEM)、N2-物理吸附、X射线光电能谱(XPS)和X射线荧光光谱(XRF)等手段对催化剂进行了表征。结果表明,阿拉伯树胶的用量可以调变Ru-Zn催化剂的粒径。最高环己烯收率随粒径的增大呈火山型变化趋势。当阿拉伯树胶与RuCl3·xH2O的质量比为0.033时,Ru-Zn催化剂的最佳粒径为4.0 nm,最高环己烯收率达59.6%。且该催化剂具有良好的重复使用性能。

| Abstract: | A nano-sized Ru-Zn catalyst was prepared by a co-precipitation method and the effect of arabic gum modification on the performance of Ru-Zn catalysts was investigated. The catalysts were characterized by X-ray diffraction (XRD), transimission electron microscopy (TEM), N2 physisorption, X-ray photoelectron spectroscopy(XPS), and X-ray fluorescence (XRF). It was found that the dosage of arabic gum could tune the particle size of the Ru-Zn catalysts. The maximum cyclohexene yield showed a volcanic-type variation tendency with the particle size of Ru-Zn catalysts increasing. When the mass ratio of arabic gum to RuCl3·xH2O was 0.033, a Ru-Zn catalyst with a optimum particle size of 4.0 nm was obtained, and a maximum cyclohexene yield of 59.6% was achieved. Moreover, the catalyst exhibited the excellent reusability. |
