PROCESS FOR ISOLATING METALLIC RUTHENIUM OR RUTHENIUM COMPOUNDS FROM RUTHENIUM-CONTAINING SOLIDS

摘要

ABSTRACT Process for Isolating Metallic Ruthenium or Ruthenium Compounds fromRuthenium-Containing SolidsThe present invention relates to a process for mobilizing metallic ruthenium orruthenium compounds from solids to form volatile ruthenium compounds by means of a gas stream containing a hydrogen halide and carbon monoxide, preferably hydrogen chloride and carbon monoxide, and for isolating the previously mobilized ruthenium compounds, preferably by deposition with cooling, e.g. in relatively cold zones, in particular on relatively cold surfaces, absorption in suitable solutions or adsorption on suitable support materials.Fig. None
