monolithic catalyst, in particular trägerkörper, a majority of tortuous bulk package

摘要

Honeycomb structure comprising a plurality of liquid permeable channels, especially catalyst supports consisting of at least partially structured sheet metal plates, arranged in a casing. The honeycomb structure has at least three bundles (stacks) (8a,8b,8c) of metal sheets (3,4). At least three of the bundles (8a,8b,8c,..) are each folded around bending lines (2a,b,c;32a,b,c etc.) in the central region of the honeycomb structure, running in the same direction in the peripheral region. The honeycomb structure can comprise four or more folded interlaced bundles (8a,8b,8c....). -
