ABSTRACT:
The present invention provides a process for producing supported ruthenium, which comprises recovering a ruthenium compound from supported ruthenium used as a catalyst in production of chlorine by oxidation of hydrogen chloride with oxygen, and supporting the ruthenium compound on a carrier; and a process for producing chlorine, which comprises producing a supported ruthenium catalyst by the process mentioned above and oxidizing hydrogen chloride with oxygen in the presence of the supported ruthenium.
