Abstract: The rate of reaction between cyclopropane and hydrogen was measured in a flow system on unsupported Ru, Ru/SiO2, andRu/MgO. The effect of the addition of Au to Ru/MgO was also investigated. The temperature was in the range 30-170 [deg]C; partial pressures were 0.01 cp PH2 3H6 + H2 --> C3H8, (1) cyclo-C3H6 + 2H2 --> CH4 + C2H6, (2) cyclo-C3H6 + 3H2 --> 3CH4. (3)At low temperatures (110 [deg]C), reaction (3) was also detected. Ruthenium particle size and presence of Au on the surface were found to have a strong influence on reaction (3), while reactions (1) and (2) were unaffected. It is suggested that, on Ru, reactions (1) and (2) have the same intermediate or they require a surface site having the same geometry.
