Abstract:
The concepts of the effect of the adsorption of the reaction medium components on the selective hydrogenation of acetylene to ethylene under the action of supported palladium catalysts have been discussed. The role of interstitial solid solutions of carbon and hydrogen in palladium, which are formed upon contact of the catalyst with the reaction medium, in the occurrence of mass transfer processes between the surface and the subsurface layer of the active component has been shown. The ratio of activation barriers to ethylene desorption/adsorption processes, which determines the acetylene hydrogenation selectivity, can vary depending on the structure of palladium nanoparticles and the electronic state of Pd. In addition, changes in the electronic state affect the energy of the activated desorption of ethylene from palladium particles, and their structural features determine the energy of the activated adsorption and subsequent hydrogenation of ethylene to ethane.
