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.
