<p><P>PROBLEM TO BE SOLVED: To reduce the cost of a catalyst when chlorine is produced by using supported ruthenium, which is produced by supporting a ruthenium compound or metallic ruthenium on a carrier, as the catalyst. <P>SOLUTION: A supported ruthenium can be produced by collecting a ruthenium compound from a supported ruthenium which has been used as a catalyst in the production of chlorine by oxidation of hydrogen chloride with oxygen, and then supporting the ruthenium compound on a carrier. Chlorine can be produced by oxidizing hydrogen chloride with oxygen in the presence of the supported ruthenium. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
