摘要： [Problem] To suppress the generation of turbulent flow that does not contribute to the purification of exhaust gas to decrease the pressure loss, and to decrease the amount of the catalyst applied to the region that does not contribute to the purification of exhaust gas.
[Solution] A honeycomb core for carrying a catalyst, comprising a flat metal foil and a corrugated metal foil, the flat metal foil and the corrugated metal foil being layered, wherein the corrugated foil is configured by repeating a concavo-convex shaped part including a first top surface that is in contact with one of the flat foils adjacent in a layering direction, a second top surface that is in contact with another flat foil adjacent in the layering direction and is disposed at a position where the second top surface avoids the first top surface as viewed in the layering direction, and an inclined leg surface that has one end connected to the first top surface through a first bent part and another end connected to the second top surface through a second bent part, and extends in a direction inclined with respect to the first top surface and the second top surface, and has an offset part having different wave phases between front and rear in an axial direction of the honeycomb core,the first bent part and the second bent part each have a R shape,a radius of curvature R1 of an inner edge of the first bent part and a radius of curvature R2 of an inner edge of the second bent part satisfy the following conditional expressions (1) and (2), respectively, and a separation distance h in the layering direction between the first top surface and the second top surface and a separation distance S between a pair of the inclined leg surfaces connected to the first top surface through the first bent parts satisfy the following conditional expression (3) :0.02 (mm) ≤ R1 ≤ 2.0 (mm) (1),0.02 (mm) ≤ R2 ≤ 2.0 (mm) (2), and 1.5 ≤ S/h ≤ 10 (3).

摘要： [Problem] To protect the gas-inlet-side edge surfaces of a catalyst support having an offset structure from wind erosion.
[Solution] A base for supporting a catalyst for exhaust gas purification, the base including a honeycomb structure obtained by superposing a metallic flat foil and a metallic wavy foil, characterized in that the wavy foil has offset portions where any adjoining two of the wave phases arranged in the axial direction of the honeycomb structure are offset from each other. The base is further characterized in that an oxide coating film has been formed in a given range of these offset portions which includes exposed edge surfaces that are exposed on the gas-inlet side, that the oxide coating film includes 30-99.9 mass% first alumina, with the remainder comprising at least one of second aluminas, Fe oxides, and Cr oxides, that the first alumina comprises α-alumina, that the second aluminas comprise one or more of γ-, θ-, χ-, δ-, η-, and κ-aluminas, and that the given range extends from the exposed edge surfaces to a distance of at least 2 mm therefrom along the gas flow direction.

摘要： [Problem] The purpose of the present invention is to provide a catalyst block having little distortion in the outside surface.
[Solution] Provided is a catalyst block for cleaning exhaust gas characterized by having: a square-shaped honeycomb core provided with first - fourth outside surfaces; a first plate attached to the first outside surface; a second plate attached to the second outside surface; and an exterior frame disposed along the outer periphery of the firm and solid honeycomb core formed from the honeycomb core, the first plate and the second plate, said exterior frame being provided with a recessed part that at least encases the first plate, the second plate, the third outside surface and the fourth outside surface. The catalyst block is also characterized in that a catalyst is supported in the honeycomb core, the first plate and the second plate, and the catalyst is not supported in the exterior frame.
