摘要: Abstract The hydrogenation of benzene, naphthalene and biphenyl over monometallic (Pt, Rh, Ru) bimetallic Ru-Pd, Ir, Re ) catalysts supported on γ-Al2O3 or TiO2 is investigated in a three-phase slurry reactor at temperature 300 °C hydrogen pressure 66 atm. Under the conditions employed this study, primary metals platinum was found to possess highest specific activity while be most reactive molecule. benzene rhodium were structure insensitive reactions. In cases, formulations exhibit significantly higher as compared their counterparts. enhancement factor larger when formations opposed Al2O3 carriers. Bimetallic catalysts, especially those containing rhenium also enhanced resistance sulfur poisoning.
