| Abstract: | Hydrogenation of benzene, toluene, o,m and p-xylene over Pt, Pd and Pt–Pd/Al2O3 catalysts has been studied. Experimental data show that when Pd is added to Pt catalysts, a decrease in activity and changes in selectivity occur. This is explained by the formation of electron-deficient and electrorich metallic species.
