Abstract
Disclosed herein is a method for the stabilizing treatment of a catalyst comprising washing the catalyst with hot washing water following the preparation of the catalyst, the catalyst being composed principally of chromium oxide and used in the production of chlorine by the oxidation of hydrogen chloride with an oxygen-containing gas, thereby improving its catalytic activity and prolonging its life.
