Naphthalene hydrogenation reactivity of rhodium-rhenium and ruthenium-rhenium formulations dispersed on doped titania carriersNaphthalene hydrogenation reactivity of rhodium-rhenium and ruthenium-rhenium formulations dispersed on doped titania carriers Peer-Reviewed Journal Publication Δημοσίευση σε Περιοδικό με Κριτές 2015-10-261993enThe hydrogenation of naphthalene over Rh-Re and Ru-Re bimetallic catalysts, formulated on W6+-doped TiO2 carriers, is investigated in a slurry reactor at a temperature of 573 K and a pressure of 65 bar. It is shown that the hydrogen adsorption capacity of both catalysts increases with dopant concentration in the TiO2 matrix, in the range 0–0.7 at.-%. Naphthalene hydrogenation activity is also enhanced as a result of carrier doping, especially of the Ru-Re catalyst. The activity of these catalysts in the hydrogenation of an actual coal-liquid distillate cut is also found to be superior, as compared to corresponding catalysts on undoped carriers or a commercial Co-Mo/Al2O3 catalyst. http://creativecommons.org/licenses/by/4.0/Applied Catalysis A: General952211-220 Koussathana M.
