  • SCR catalyst for removing nitrogen oxides and method for producing same
    Patent number: 11148122
    Abstract: A SCR catalyst for removing nitrogen oxides comprises: a carrier prepared from a support in which Ti-PILC is mixed with titania; and a catalyst material on the carrier, wherein the catalyst material contains an active material of a vanadium component and a co-catalyst of a tungsten component. On the basis of the total weight of the catalyst, the support Ti-PILC is contained at 0.01-40 wt %, and the support titania is contained at 50 to 90 wt %. In addition, a method for producing a SCR catalyst for removing nitrogen oxides comprises the steps of: preparing a carrier by using a support in which Ti-PILC is mixed with titania; and supporting a catalyst material on the carrier. The present disclosure provides: a SCR catalyst for removing nitrogen oxides, which has an excellent nitrogen oxide removing performance and a high producing convenience; and a method for producing the same.
