摘要

用共沉淀法制备了纳米Ru-Zn催化剂

考察了不同浓度NaOH同时作沉淀剂和还原介质对苯选择加氢制环己烯Ru-Zn催化剂性能的影响

NaOH浓度可以调变Ru-Zn催化剂的Zn含量、粒径和孔径

进而影响Ru-Zn催化剂的苯选择加氢制环己烯性能。NaOH含量为15%时制备的Ru-Zn催化剂在优化的反应条件下获得了61.5%的环己烯收率

而且该催化剂具有良好的重复使用性能。

Abstract

Ru-Zn catalysts were prepared by the co-precipitation method

and the effect of the different NaOH concentration as precipitant and reduction medium on the performance of Ru-Zn catalyst for selective hydrogenation of benzene to cyclohexene was investigated. The catalysts were characterized by X-ray diffraction (XRD)

N2 physisorption (BET)

X-ray fluorescene (XRF) and transmission electron micrograph (TEM). It was found that the concentration of NaOH could modify the Zn contents

particle size and pore diameter

and then affect the performance of Ru-Zn catalysts. The Ru-Zn catalyst prepared with the NaOH concentration of 15% gave a high cyclohexene yield of 61.5%. Moreover

this catalyst exhibited the excellent reusability.
