Hydrogenation of acetylene in an artificial acetylene-ethylene-deuterium mixture on three types of 0.04% Pd on alumina catalysts has been investigated. The effect of regeneration with oxygen, the hydrogenation temperature, ethylene fouling, and the effect of hydrogen vs deuterium were studied. It was established that supported palladium behaves similarly to the previously studied palladium black (Margitfalvi, J., Guczi, L., and Weiss, A.H., J. Catal. 72 185 (1981)) concerning the effect of carbonaceous deposits which affect the amount of surface hydrogen available for the formation of ethylidyne species. This form is responsible for the diminished selectivity. All factors removing this hydrogen result in an increased selectivity.
