NaOH浓度对苯选择加氢制环己烯Ru-Zn催化剂性能的影响
Effect of NaOH concentration on performance of Ru-Zn catalyst for selective hydrogenation of benzene to cyclohexene
摘要
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.关键词
