ABSTRACT:
A carrier matrix for a catalytic reactor for the purification of the exhaust gas of internal combustion engines, comprising a flat foil and a corrugated foil arranged in alternating layers. Exhaust gas flows through the ducts formed by the corrugations of the corrugated foil and the flat foil surface. The corrugations have a plurality of segments fluidly connected behind one another in flow direction, but are transversely staggered with respect to flow direction. This staggered arrangement increases the turbulence of the gas flowing through the ducts, thereby increasing the effectiveness of the matrix. The matrix can be manufactured in a simple manner yet permits a good utilization of the catalyst materials coated on the foils.
