Abstract:
The invention relates to a process for regenerating a hydrogen chloride oxidation catalyst comprising ruthenium oxide on a support material, which comprises the steps a) reduction of the catalyst in a gas stream comprising hydrogen chloride and optionally an inert gas at a temperature of from 100 to 800° C., b) recalcination of the catalyst in an oxygen-comprising gas stream at a temperature of from 150 to 800° C.
