Abstract

Process for the preparation of selective hydrogenation catalysts, destined for the selective hydrogenation of unsaturated impurities contained in ethylene gases, characterized in that it comprises impregnating a support of alumina or of silica and of alumina, which has a specific surface area of between a few m2/g. at 150 m2/g with solutions of compounds such as palladium and vanadium, in one or several times, and subsequently calcining the supports so impregnated until their proportion in palladium is between 100 and 800 ppm and their proportion in vanadium is between 50 and 100 ppm.
