Abstract: The present invention relates to a method for manufacturing a ruthenium oxide-supported catalyst for preparing chlorine, and more particularly, to a method for manufacturing a catalyst and a catalyst manufactured thereby, wherein the catalyst includes a ruthenium ingredient of which a support level on an outer surface of a support is significantly improved, and the use of the catalyst in preparing chlorine can provide a high conversion rate of chlorine even at a low reaction temperature. According to an embodiment of the present invention, the method for manufacturing a ruthenium oxide-supported catalyst for preparing chlorine may include the steps of: (a) dissolving a ruthenium compound in an organic solvent to prepare a solution and supporting the same on at least one support selected from titania and alumina; (b) performing drying thereon after the supporting; and (c) performing calcining thereon after the drying. According to an embodiment of the present invention, in particular, it is possible to provide a simplified process by manufacturing a catalyst including ruthenium oxide only at each outer surface layer of a titania support without alkali pretreatment, thereby exhibiting an advantageous effect in terms of scale-up.

Abstract: The present invention relates to a catalyst for obtaining chlorine (Cl2) through an oxidation reaction of hydrogen chloride (HCl), and more particularly, to an oxidation reaction catalyst for preparing Cl2 from HCl by addition of a second heterogeneous material to a RuO2-supported catalyst using TiO2 as a support, and a preparation method therefor. According to an embodiment of the present invention, a hydrogen chloride oxidation reaction catalyst for use in a method for preparing chlorine by oxidizing hydrogen chloride includes a support and a heterogeneous material in an active ingredient. The catalyst according to the present invention has both increased catalytic activity at a low temperature and enhanced thermal stability, and thus a catalyst having improved durability such as thermal stability at a high temperature is provided. Therefore, since thermal stability is secured, the performance of the catalyst is maintained for a long time even at a high temperature.
