Margitfalvi, József L. Margitfalvi, Mihály Hegedűs, Yurii A. Ryndin, Yurii A. Ryndin] Summary: Transformation of n-hexane over Al2O3and SiO2supported Pt, Pt+Ga and Ir+Pt+Ga catalysts was studied in a continuous-flow reactor operated under slug-pulse mode at 520°C. Bimetallic catalysts were prepared by introducing first Ga(OEt)3and then diallylplatinum as precursor compounds. Iridium was then introduced viadecomposition of Ir4(CO)12adsorbed onto Pt+Ga catalysts. The addition of Ga to Pt/SiO2catalyst decreased hydrogenation, aromatization and hydrogenolysis selectivity. Over Pt/Al2O3catalyst Ga increased hydrogenolysis selectivity and decreased isomerization and C5-cyclization. The main effect of Ir was to increase hydrogenolysis selectivity and the stability of catalysts.</o:p> Springer-Verlag/Akadémiai Kiadó, 2006 hydrogenolysis nationallicence catalyst nationallicence aromatization nationallicence n-Hexane nationallicence Pt+Ga/SiO2 nationallicence Pt+Ga/Al2O3 nationallicence Ir+Pt+Ga/SiO2 nationallicence Ir+Pt+Ga/Al2O3 nationallicence Gőbölös Sándor Chemical Research Center, Institute of Surface Chemistry and Catalysis, Hungarian Academy of Sciences, 1525 Budapest, POB 17, Hungary aut Margitfalvi József L.
