摘　　要：A supported amorphous Ru-Co/ZrO 2 catalyst was prepared by using formaldehyde as reduetant. The amorphous character of the catalyst was estimated by XRD, TG-DTA and SEM. The amorphous Ru-Co/ZrO 2 catalyst has higher selectivity than Ru/ZrO 2 in the selective hydrogenation of benzene to cyclohexene when the experiments were run in simulated production conditions. Presence of Co in the catalyst favored the selectivity of Ru-Co/ZrO 2 but decreased its activity.A supported amorphous Ru-Co/ZrO 2 catalyst was prepared by using formaldehyde as reduetant.
