HYBRID CARRIER FOR CATALYTIC DEVICE

摘要

PROBLEM TO BE SOLVED: To obtain a low-cost durable hybrid carrier for a catalytic device having satisfactory efficiency and not causing damage against a high temp. of the central part of the carrier especially due to an accidental fire in an engine. SOLUTION: A honeycomb metallic carrier 11 formed by rolling a metallic flat sheet and a metallic corrugated sheet in layers, a ceramic carrier 12 of a ceramic material and a corrugated sheet 1 for buffering coating the outside of the ceramic carrier 12 are housed in an outer cylinder 15 and a stopper 13 is fixed so as to prevent the ceramic carrier 12 from moving toward the downstream side of the axial direction. A catalyst is carried on the two carriers 11, 12 and the corrugated sheet 14 to form the objective hybrid carrier.
