    Abstract: The invention relates to a catalyst for the catalytic oxidation of hydrogen chloride with oxygen into chlorine, containing ruthenium on a carrier, characterized in that the catalyst contains 0.01 to 10 wt % of silver and/or calcium as (a) doping agent(s). The carrier is preferably made substantially of alpha-aluminum oxide. The catalyst preferably contains a) 0.1 to 10 wt % of ruthenium, b) 0.01 to 5 wt % of silver and/or 0.01 to 5 wt % of calcium, c) 0 to 5 wt % of one or more alkaline earth metals, d) 0 to 5 wt % of one or more alkali metals, e) 0 to 5 wt % of one or more rare earth metals, f) 0 to 5 wt % of one or more additional metals selected from the group consisting of nickel, palladium, platinum, iridium, and rhenium, the percentages being relative to the total weight of the catalyst.

    Abstract: The invention relates to a method for recovering ruthenium from a spent ruthenium-containing catalyst which contains ruthenium in the form of ruthenium oxide on a support material that is poorly soluble in mineral acid. Said method comprises the following steps: a) the catalyst containing ruthenium oxide is reduced in a gas stream containing hydrogen chloride and an optional inert gas at a temperature ranging from 300 to 500°C; b) the catalyst that has been reduced in step a) and contains metallic ruthenium on the poorly soluble support material is treated with hydrochloric acid in the presence of a gas containing oxygen such that the metallic ruthenium on the support is dissolved in the form of ruthenium(III) chloride and is recovered in the form of aqueous ruthenium(III) chloride solution; c) if necessary, the ruthenium(III) chloride solution obtained in step b) is further processed.
