Abstract (en)

[origin: CN101663242A] Process to recover ruthenium in the form of ruthenium halide, particularly ruthenium chloride, from a ruthenium-containing supported catalyst material comprising: a) chemically decomposing the ruthenium-containing supported catalyst material; b) producing a raw ruthenium salt solution; c) purifying the raw ruthenium salt solution and optionally stripping gaseous ruthenium tetroxide from the raw ruthenium salt solution; and d) treating the purified ruthenium compound obtained in c), particularly the ruthenium tetroxide, with hydrogen halide or hydrohalic acid to obtain ruthenium halide, particularly with hydrogen chloride or hydrochloric acid to obtain ruthenium chloride.
