Abstract:
An exhaust gas purification material according to the present invention is provided with a particulate filter  10  that traps particulate matter in exhaust gas and contains an SCR catalyst for adsorbing ammonia and reducing NOx in the exhaust gas. A maximum allowable adsorption amount of ammonia adsorbable by the filter  10  differs between an upstream portion  10 a  of the filter  10  including an exhaust gas inlet-side end  10 c , and a downstream portion  10 b  of the filter  10  including an exhaust gas outlet-side end  10 d . The SCR catalyst contained in the upstream portion  10 a  and the SCR catalyst contained in the downstream portion  10 b  are qualitatively different. A ratio (B/A) of a maximum allowable adsorption amount of ammonia A in the upstream portion  10 a  and a maximum allowable adsorption amount of ammonia B in the downstream portion  10 b  satisfies the relationship 1.1≤(B/A)≤2.

Claim (Index 2):
The exhaust gas purification material according to  claim 1 , wherein a value of ratio (B/A) of the maximum allowable adsorption amount of ammonia A in the upstream portion and the maximum allowable adsorption amount of ammonia B in the downstream portion satisfies 1.1\u2264(B/A)\u22641.5.
