Abstract

Catalysts for the purification of ethylene containing copper and zinc, optionally one or more promoters or supports. These catalysts are produced by precipitation, drying, calcination and compression, optionally with the addition of additives, the compressed catalyst particles are calcinated at a temperature between from 300 to 700° C.
