Title: Metal carrier
Inventor: OZAKI YUKIKATSU
IPC: B01D53/86
Filed: 1994-02-24
Abstract: PURPOSE:To enhance durability by increasing the strength of a metal catalyst carrier and preventing it from being damaged by scoping. CONSTITUTION:When a heat resistant metal corrugated plate 2 and a heat resistant metal plain plate 3 are alternately laminated for bearing a catalyst and the laminate is wound spirally to form a honeycomb form 1, the outermost peripheral layer of the honeycomb form 1 is designed to be the corrugated plate 7, and the pitch P2 of a corrugated plate 7 in the outermost peripheral part is also designed to be smaller than the pitch P1 of the corrugated plate 2 in the inner part.
