Exhaust gas purifying apparatus of an internal combustion engine, an exhaust gas purification method, and s min capturing material for an internal combustion engine

An object of the present invention is to provide a suitable novel exhaust gas purifying apparatus for suppressing the performance degradation due to S content of the NOx purification catalyst that way, and the exhaust gas purifying catalyst. Relative to the S content capturing material of 1.5 mol, and the 150ppmSO
