Preparing and testing of ruthenium colloid catalysts for the production of cyclohexane by selective benzene hydrogenation
Liquid phase hydrogenation of benzene on carrier fixed ruthenium colloid catalysts suspended in an aqueous solution of sodium hydroxide proceeds with high cyclohexene selectivity (>50 %) at 50 % benzene conversion. The catalysts are prepared by adsorbing a stabilized ruthenium metal colloid on lanthanium oxide.
