  • Exhaust-gas purifying catalyst
    Patent number: 7585478
    Abstract: An exhaust-gas purifying catalyst includes a mantle, two or more honeycomb-shaped supports fastened in the mantle so as to be separated at intervals, and a catalytic layer disposed on the respective honeycomb-shaped supports. The honeycomb-shaped supports include a first honeycomb-shaped support, disposed on a most upstream side of the mantle with respect to a flow of exhaust gases, and a second honeycomb-shaped support, disposed next to the first honeycomb-shaped support on a downstream side of the mantle with respect to the flow of exhaust gases. The catalytic layer includes a loading layer formed on the respective honeycomb-shaped supports, and a catalytic ingredient loaded on the loading layer. The catalytic layer disposed on the first honeycomb-shaped support includes at least Rh in a loading amount of 0.8 g or more with respect to 1 L of an apparent volume of the first honeycomb-shaped support.
