摘要

"CATALYLERS FOR ETHYLENE PURIFICATION CONTAINING COPPER AND ZINC, PROCESS FOR ETHYLENE PURIFICATION WITH CATALYLERS, AND USE OF CATALYLERS". Copper and zinc-containing ethylene purification catalysts, optionally one or more promoters and supports, produced by precipitation, drying, calcination and compression, optionally with the addition of additives, wherein the compressed catalyst particles are subsequently calcined at a temperature. between 300 and 700 198 C.
