| titleOfInvention | Gas engine exhaust gas three-way catalyst and gas engine exhaust gas purification method |
| abstract | (57) [Summary] [Purpose] A three-way catalyst used for exhaust gas purification of a gas engine using a gas containing methane as a main component (methane main component gas) as a fuel, and an exhaust gas purification method using the same. The purpose is to provide. The catalyst of the present invention is a three-way catalyst for exhaust gas purification of a gas engine using methane-based gas as a fuel, which contains at least Pt, Rh and Ce in a washcoat layer coated on a honeycomb carrier. , The washcoat layer contains at least two types of catalyst particles supported so that Rh / Pt concentration ratios are different, and Pt is contained in a specific ratio, Containing Rh and Ce. According to the present invention, the conversion activity of methane near the stoichiometric air-fuel ratio is kept high, the window does not deviate from the stoichiometric air-fuel ratio for a long period of time, and NO, CO, and methane can be stably purified for a long period of time. it can. |
