ResumoSupported Pt, Pd, Rh and Ir catalysts have been studied in the hydrogenation of acetylene and the effect of the particle size on this reaction was established. The metals studied can be subdivided into two groups, Pd and Pt on the one hand and Ir and Rh on the other. The latter group shows effects that can most likely be explained by an influence of the particle size on the intermediate of direct hydrogenation to ethane, whereas in the case of Pd and Pt the effect of deposition of carbonaceous layers prevails.
