Abstract
Abstract Disclosed is a catalyst support for catalytic reactors for cleaning exhaust gas, characterized in that flat steel band plates and corrugated steel band plates, each of which is heat-resistant and covered with catalyst, are superposed in such a way that one comes on top of the other alternately, and brazed together on their center line running along the longitudinal direction thereof.
