Abstract

Ru-based magnetic(Ru/γ-Fe2O3-SiO2-γ-Al2O3)egg-shell catalysts were prepared by the impregnation method.A magnetically stabilized bed(MSB)unit was designed and used to characterize selective hydrogenation of benzene.The effects of catalyst preparation parameters and reaction conditions on selective hydrogenation of benzene were investigated.The results showed that the state of chain operation in MSB increased the selectivity for cyclohexene obviously

which verified that the magnetic ruthenium-based catalysts and magnetically stabilized bed had a good prospect of industrial applications.
