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 1):
An exhaust gas purification material that is disposed in an exhaust passage of an internal combustion engine, and purifies exhaust gas emitted by the internal combustion engine, the exhaust gas purification material comprising:\n a particulate filter that traps particulate matter in the exhaust gas and contains an SCR catalyst for adsorbing ammonia and reducing NOx in the exhaust gas, wherein an upstream portion of the filter including an exhaust gas inlet-side end, and a downstream portion of the filter including an exhaust gas outlet-side end, each contain an SCR catalyst,\n the SCR catalyst contained in the upstream portion and the SCR catalyst contained in the downstream portion are qualitatively different, and \n a ratio (B/A) of a maximum allowable adsorption amount of ammonia A in the upstream portion and a maximum allowable adsorption amount of ammonia B in the downstream portion satisfies the relationship 1.1\u2264(B/A)\u22642.
