ABSTRACT:
A device for catalytically converting automotive exhaust gas pollutants to harmless substances comprises a plurality of catalyst units or sections of selected limited length which are disposed in alternate sequence with heat-dissipating means within a container so that the automotive exhaust gasses can be passed through the catalyst sections and heat-dissipating means in sequence. Each catalyst section is formed from a pair of corrugated strips of catalyst material which are wrapped together in a jelly-roll configuration. The paired catalyst strips have corrugations which are disposed obliquely relative to each other so that obliquely intersecting passage portions provided by the corrugations cooperate in forming passages of continuously varying cross-sectional area extending through each catalyst section.
