A metal honeycomb carrier comprising a metal outer casing having inserted thereinto a metal honeycomb structure consisting of a metallic flat foil and a metallic corrugated foil, wherein perforations in an opening ratio of 30 to 60% are provided in either one or both of the flat foil and the corrugated foil.

Metal carrier catalyst for cleaning exhaust gas

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.

Exhaust-gas purifying catalyst

An exhaust gas purifying apparatus includes an exhaust pipefor forming an exhaust way, and a catalyst disposed in the exhaust wayfor purifying an exhaust gas. The catalyst includes the first honeycomb catalyst portionand the second honeycomb catalyst portion. The first honeycomb catalyst portionhas an outer circumferrencial surface for forming a blowing passagewith an inner circumferrencial surface of the exhaust pipe. The radial cross sectional area in the catalyst region of the first honeycomb catalyst portionis set in the 1/5&#x2013;2/3 range with respect to the radial cross sectional area of a flowing way defined by the inwall surface of the first mounting positionplaced in the exhaust way, with the first honeycomb catalyst portionbeing removed.
