ADSORPTION DATA EXTRACTED FROM KINETIC-EQUATIONS OF SOME HYDROCARBON CONVERSIONS ON NICKEL

Adsorption equilibrium constants and adsorption enthalpies have been calculated from kinetic data of cyclohexane dehydrogenation and ethane hydrogenolysis on metallic nickel. From these data the bond strength of hydrogen and carbon with the active sites of nickel and the activation barrier of C-H and H-H bond dissociation were calculated by the recently developed method of shustorovich. The calculated data indicate that the active sites for dehydrogenation differ (or in part differ) from those of hydrogenolysis.
