The Effect of Modifiers on Benzene Selective Hydrogenation over Ru/ZrO_2·xH_2O

Based on the Ru/ZrO_2·xH_2O catalyst prepared by the coprecipitation method, the influences of some inorganic and organic modifiers on benzene selective hydrogenation have been studied. It is found that the presence of zinc sulfate during catalyst reduction drastically improves the cyclohexene yield to 43.4%. The addition of a suitable amount of methanol in the benzene-water system can moderately increase cyclohexene yield. While the promoting effect of the inorganic promoters such as zinc, chromium and cobalt is minimal.
