More Information
Summary:A supported ruthenium oxide catalyst selected from the group consisting of (1) a supported ruthenium oxide catalyst comprising TiO2 which contains the rutile crystal form, and which is obtained by calcination at a temperature of at least 550 DEG C, as a carrier; (2) a supported ruthenium oxide catalyst having a carbon monoxide adsorption amount of at least 87.5 ml per one gram of ruthenium contained in the catalyst; (3) a supported ruthenium oxide catalyst obtained by a preparation process comprising the steps of supporting a ruthenium compound on a carrier, calcining the supported one at a temperature of at least 200 DEG C in an oxidizing gas atmosphere, an inert gas atmosphere or a reducing gas atmosphere, treating the calcined one with a mixed solution of hydrazine and an alkaline compound, and oxidizing the hydrazine-treated one. These catalysts have a high catalytic activity and thus produce chlorine in a smaller amount at a lower temperature.
