Abstract The zinc oxide-copper catalysts under investigation included a series of catalysts of different copper contents prepared by kneading zinc oxide powder with copper hydroxide cake (the “kneaded series”), and two other catalysts prepared by the impregnation and the coprecipitation methods. Only the catalysts of the kneaded series show a high activity in the carbon monoxide-shift conversion, provided the catalysts contain appropriate amounts of copper. The observed dependency of the catalytic activity on the copper content can be interpreted in view of the catalyst scheme in which the copper forms its own fine particles among the original zinc oxide particles. On the basis of this picture, the study was then extended to other copper-containing catalysts; an active alumina-copper catalyst could be produced by kneading the cake with alumina powder with a high specific surface area.
