| Abstract: | A load ruthenium catalyst was prepared via chemical reduction and was used in the selective hydrogenation of benzene to cyclohexene. The effects of reaction temperature, hydrogen pressure, stirring rate and reaction time on benzene conversion, cyclohexene selectivity and yield were studied. The results showed that the conversion of benzene and the selectivity and yield of cyclohexene can be achieved as 76.27% ,68.33% and 52.12% ,respectively, under the optimal conditions as followed: reaction temperature 140℃, hydrogen pressure 6.0 MPa, stirring rate 900 r/min, reaction time 20 min. |
