ABSTRACT:
An improved carrier matrix for catalysts is described wherein layers are disposed one on top of the other consisting of highly temperature resistant and non-scaling steel formed into a smooth screen into which closed hollow or open supporting profiles of a larger cross section than the screen are woven in or on at parallel distances. Layers of screens provided with profiles may be combined with layers of flat screens or smooth or corrugated sheet metal. The carrier matrix may be coated with a catalytically active carrier such as gamma-aluminum oxide and then receive a coating of a catalytically active metal whereby the resulting product may be used to treat auto exhaust gases for purification.
