| description | A selective catalytic reduction catalyst composition for converting oxides of nitrogen (NOx) in an exhaust gas using a nitrogenous reductant, which catalyst composition comprising a mixture of a first component and a second component, wherein the first component is the H-form of an aluminosilicate chabazite zeolite (CHA); or an admixture of the H-form of an aluminosilicate mordenite zeolite (MOR) and the H-form of an aluminosilicate chabazite zeolite (CHA); and the second component is a vanadium oxide supported on a metal oxide support, which is titania, silica-stabilized titania or a mixture of titania and silica-stabilized titania, wherein the weight ratio of the first component to the second component is 10:90 to 25:75. |
