A support matrix for a catalytic reactor for scrubbing exhaust gases in an internal combustion engine, composed of layers of alternating steel panels at least some of which are coated with a catalyzer and at least one of which is corrugated so as to form flow channels for the exhaust gases. In order to increase the turbulence of the flow in the channels of the matrix, the smooth panel and/or the corrugated panel is subdivided into narrow strips which lie adjacent to one another and are encountered sequentially by the inflowing exhaust gas. Furthermore, the exhaust gases which are divided into small streams may recombine between the strips and thus encounter renewed admixture. They are then redivided in the subsequent strip resulting in an overall intensive contact of each gas stream thread with a surface of the subsequent narrow strip, thereby substantially improving the catalytic efficiency.

A support matrix for a catalytic reactor for scrubbing exhaust gases from internal combustion engines, comprising alternating steel panels coated with catalyst, at least one of said panels being corrugated, and at least one of the steel panels being provided with projections and/or depressions, said depressions being apertures and wherein according to the invention said apertures extend over the entire longitudinal extent of the panel, thereby separating at least one of said panels into narrow strips disposed at a transverse separation from one another.
