• The hydrogenation of ethylene and benzene on two series of copper-nickel alloys, i. e., massive alloys prepared physically and granular alloys prepared chemically, was carried out in order to determine the cause of the disagreement of the catalytic activities which have been found in these alloys. The adsorption of hydrogen on granular alloys was also examined to learn the heat of adsorption and the amount adsorbed; the results were compared with the activities of the alloys.<BR>The activities of massive alloys may be interpreted by the Dowden theory, but those of granular alloys could not. The activities of granular alloys were interpreted in connection with the concentration of nickel at the surface, which can be considered to be different from that in the interior. It was concluded that the amount of hydrogen adsorbed, the heat of adsorption, and the catalytic activity of granular alloy are related to the concentration of nickel at the surface.
