The Activity of Some lb and VIII-group Metals for Hydrogenations and Dehydrogenations of Oxy-compounds

The energies of activation for the catalytic dehydrogenation of different alcohols (methanol, ethanol, propanol-2, butanol-1, butanol-2) as well as for the catalytic hydrogenation of acetone and butanone to alcohols were determined on the following metals: Ag, Cu, Ni, Co , Fe. Furthermore, the energies of activation for the dehydrogenation of formic acid and o f ethanol were determined over two mixed catalysts, Ni-Ag and Ni-Cu. The results of these determinations are presented in Tables I and II and in Figures 1 and 2. They are found to be in agreement with the theory of formation of activated complexes between the reactants and catalysts if the influence of the resonance energy of these complexes is taken into consideration
