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.

Abstract: The invention relates to a method for producing chlorine in a fluidized bed reactor, a gaseous reaction mixture containing hydrogen chloride and oxygen flowing from the bottom to the top of a heterogeneous particulate catalyst that forms a fluidized bed. The invention is characterized in that said fluidized bed comprises insertion elements which divide the fluidized bed into a plurality of horizontal and vertical cells arranged in the fluidized bed reactor, the walls of said cells being permeable to gas and having openings for ensuring the exchange of particles of the heterogeneous particulate catalyst in the vertical direction in the range of between 1 and 100 liter(s)/hour per liter of reactor volume.
