Title:
HONEYCOMB BODY FOR CARRYING CATALYST AND CATALYST CONVERTER
Document Type and Number:
WIPO Patent Application WO/2017/119375
Kind Code:
A1
Abstract:
A honeycomb body for carrying a catalyst, wherein a flat foil and a wavy foil that are made of metal are layered, is characterized in that: the wavy foil is constituted by continuously forming a protruding and recessed part comprising a first top surface, a second top surface and an inclined leg surface part one end of which is continuous with the first top surface via a first curved part and the other end of which is continuous with the second top surface via a second curved part, and has an offset part wherein the phases of waves on the back and front in the axial direction of the honeycomb body are different from each other; the first curved part and the second curved part are both formed in a rounded shape, and the radius of curvature R1 for the inside edge of the first curved part and the radius of curvature R2 for the inside edge of the second curved part respectively satisfy the following conditional equations (1) and (2); and, letting h be the separation gap in the direction of lamination of the first top surface and the second top surface and S be the separation gap for the pair of inclined leg surface parts continuous with the first top surface via the first curved part, the following conditional equation (3) is satisfied. 0.02 (mm) ≤ R1 ≤ 2.0 (mm) ... (1) 0.02 (mm) ≤ R2 ≤ 2.0 (mm) ... (2) 1.5 ≤ S/h ≤ 10 ... (3)
