Ce-promoted Ru/SBA-15 catalysts prepared by a ‘‘two solvents’’ impregnation method for selective hydrogenation of benzene to cyclohexene

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, the beneficial
effect of the Ce promoter on the selectivity to cyclohexene was ascribed to the enhancement of the
hydrophilicity of the catalyst and to the electron transfer between the Ce(III) species and metallic Ru.
