Abstract (en)

[origin: WO2010142604A1] The invention relates to a method for the catalytic oxidation of hydrogen chloride with oxygen to form chloride in a fluidized bed method in the presence of a catalyst containing ruthenium on a particulate carrier made of alpha-aluminum oxide having an average particle size of 10 to 200 µm, characterized in that the catalyst carrier has a low surface roughness and can be obtained from a used catalyst, which has been used for at least 500 operating hours in a fluidized bed method.
