Abstract Ce-promoted Ru/SBA-15 catalysts were prepared by a ‘‘two solvents’’ impregnation method. In liquidphase hydrogenation of benzene, the Ce-promoted Ru/SBA-15 catalysts exhibited superior catalytic performance to the un-promoted catalyst. The optimum bulk Ce/Ru molar ratio was determined to be 0.25, at which a cyclohexene yield of 53.8% was obtained. Based on characterizations…
