| Abstract: | Bimetallic Ru-Cu catalysts supported on SiO2,  -Al2O3,  -Al2O3 have been prepared using precursors which do not contain chlorine and characterized by CO chemisorption and TPR. Catalytic activity has been tested in the propane hydrogenolysis. It has been observed that the degree of formation of bimetallic Ru-Cu aggregates depends on the support used. It is suggested that the degree of interaction between Ru and Cu is strongly influenced by the strength of the metal-support interaction. |
