CATALYST FOR CHLORINE PRODUCTION

摘要

The subject of the present invention is a copper (I) aluminate-containing catalyst to be used for the stable production of chlorine from hydrogen chloride by thermocatalytic oxidation with oxygen-containing gases, wherein the preparation procedure of the catalyst comprises an annealing step to produce a copper (I) aluminate-containing catalyst in which at least 50 wt-% of the copper altogether present in the catalyst is present as copper (I).
