Abstract:
Object and purpose are to provide an exhaust gas purification catalyst capable of efficiently removing a nitrogen oxide in a relatively low-temperature exhaust gas discharged from a marine diesel engine or the like using a reducing agent in a smaller amount than in the past. An exhaust gas purification catalyst is used in a combustion exhaust gas purification method for removing a nitrogen oxide in a combustion exhaust gas by reducing the nitrogen oxide to nitrogen, wherein an alcohol is added to the combustion exhaust gas as a reducing agent for reducing the nitrogen oxide, and is characterized in that the catalyst is composed of a support and a denitration catalytic metal supported on the support, and the support is a zeolite having a value (S) obtained by dividing a peak area (A) in an Al—OH spectrum measured with a Fourier transform infrared spectrometer (FT-IR) by a measurement support weight (W) of 1500 to 3500.
