Method for manufacturing ruthenium oxide-supported catalyst for preparing chlorine and catalyst manufactured thereby

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.
