    Abstract: A process for preparing chlorine in a fluidized-bed reactor, in which a gaseous reaction mixture comprising hydrogen chloride and oxygen flows from the bottom upward through a heterogeneous particulate catalyst forming a fluidized bed, wherein the fluidized bed is provided with internals which divide the fluidized bed into a plurality of cells arranged horizontally in the fluidized-bed reactor and a plurality of cells arranged vertically in the fluidized-bed reactor, with the cells having cell walls which are permeable to gas and have openings which ensure an exchange number of the heterogeneous, particulate catalyst in the vertical direction in the range from 1 to 100 liters/hour per liter of reactor volume, is proposed.

    Abstract: An oxidation process employing a mechanically stable catalyst of an active metal or combination of active metals supported on aluminum oxide, which is predominantly alpha-aluminum oxide, is provided. The active metal or metals is optionally one or a mixture of ruthenium, copper, gold, an alkaline earth metal, an alkali metal, palladium, platinum, osmium, iridium, silver, and rhenium. The process is applicable to the oxidation of hydrogen chloride to chlorine in a Deacon process.

    Abstract: The stream containing hydrogen chloride (I) and the stream containing oxygen (II) are fed into an oxidation zone. The hydrogen chloride is oxidized to chlorine. A gas and a water-free gas streams are remained through the cooling and drying. The stream reversal contains chlorine-rich, chlorine, oxygen and carbon dioxide, and the liquefaction is carried out by compression and cooling (6). The gas and the water-free gas streams contain chlorine, water, oxygen, carbon dioxide and inert gases. The Gas/liquid stream is separated into a gas stream containing chlorine, oxygen, carbon dioxide and inert gases and into a fluid stream containing chlorine, oxygen and carbon dioxide. The gas stream is fed into a membrane separation unit (9) and separated into the stream reversal and chlorine-poor, chlorine, oxygen and carbon dioxide containing gas by membrane separation. The liquid stream is separated into a chlorine stream and a stream containing oxygen and carbon dioxide by distillation. The chlorine-poor and the gas stream are led into the oxidation zone, and the chlorine poor is removed.
