This paper presents a new metallic catalyst substrate design that allows an integrated mixing behaviour and flow homogenisation within the substrate. In addition it offers a high mass transfer from the flow to the interior substrate surface.The design consists of corrugated walls with crosswise orientation of adjacent layers. The walls are permeable so that their high specific surface is directly accessible for the flow and consequently the length for diffusion is reduced and the mass transfer is enhanced. The crosswise corrugated design causes the intensive internal mixing of the flow within the substrate. Thereby local differences in velocity as well as in temperature and in concentration are equalized.Thus the new metallic substrate design concept offers homogeneous reaction conditions throughout the entire substrate. It allows a compact design and in case of a Diesel oxidation catalyst an additional soot reduction due to the design with permeable walls.
