Abstract
Catalysts for the purification of ethylene comprising copper and zinc and, if desired, one or more promoters and supports are produced by precipitation, drying, calcination and pressing, with or without addition of additives, and the pressed catalyst particles are subjected to further calcination at from 300 to 700° C.
Claims6
A catalyst for the purification of ethylene, comprising copper and zinc and, if desired, one or more promoters and supports and produced by precipitation, drying, calcination and pressing, with or without addition of additives, wherein the pressed catalyst particles are subjected to further calcination at from 300 to 700° C.
A catalyst for the purification of ethylene, consisting of copper and zinc, if desired partly in oxidic form, and if desired, one or more promoters and supports and produced by precipitation, drying, calcination and pressing, with or without addition of additives, wherein the pressed catalyst particles are subjected to further calcination at from 300 to 700° C.
