Abstract (en)
[origin: WO2008131856A2] The invention relates to a method for the recovery of ruthenium in the form of ruthenium halide, in particular ruthenium chloride from a supported catalyst material containing ruthenium, comprising at least the following steps: a) chemical decomposition of the catalyst material, b) production of a crude ruthenium salt solution, c) purification of the crude ruthenium salt solution and optional expulsion of gaseous ruthenium tetraoxide from said solution, d) subsequent treatment of the purified ruthenium compound contained in c), in particular the ruthenium tetraoxide with hydrogen halide or hydrohalic acid to obtain ruthenium halide, or in particular with hydrogen chloride or hydrochloric acid to obtain ruthenium chloride.
