Title:
CATALYST CARRIER BASE AND CATALYST CARRIER
Document Type and Number:
Japanese Patent JP2023020148
Kind Code:
A
Abstract:
To provide: a catalyst carrier base that includes a beam-shaped flat part which extends to a winding core and in which a hole is formed, wherein fatigue failure of the beam-shaped flat part is suppressed by a simple method; and a catalyst carrier in which a catalyst is carried on this catalyst carrier base.SOLUTION: Provided is a catalyst carrier base 1 including: a honeycomb body 4 formed by winding a flat foil 2 and a corrugated foil 3 made from metal foil; and an outer cylinder 5 disposed at a position surrounding an outer peripheral surface of the honeycomb body. The catalyst carrier base is characterized in that: a plurality of holes are formed in the flat foil 2 and the corrugated foil 3; a beam-shaped flat part 2a that is an end section of the flat foil or the corrugated foil extends to a winding core 6 of the honeycomb body; some of the plurality of holes are formed in the beam-shaped flat part 2a; and an inner diameter of the winding core 6 is 3 mm or less.SELECTED DRAWING: Figure 1
