A novel 4 wt% Ru/AlOOH catalyst was prepared by the coprecipitation method and characterized by XRD, TG/DTA, TEM and nitrogen physisorption. In liquid phase benzene partial hydrogenation, Ru/AlOOH catalyst exhibited much higher cyclohexene selectivity and moderate activity than Ru/γ-Al2O3 catalyst prepared by calcining the titled catalyst or by the wetness impregnation method. It is suggested that the surface hydroxyl groups and the large pores in boehmite be essential for a high yield of cyclohexene.

Key words: benzene, cyclohexene, hydrogenation, Ru,Ru/AlOOH, ore structure
