Metal catalyst carriers and catalyst members made therefrom

Abstract

A pliable refractory metal carrier () may have coated thereon an anchor layer () to improve adherence to the carrier () of a catalytic coating (). The conformable catalyst member () may be bent to conform to a curved or bent exhaust pipe () within which it is mounted. The pliable metal carrier may be in the form of a tube such as carrier () having perforations () formed therein, or it may be a metal strip () which is folded into accordion pleats () and has perforations () formed therein. The perforations () serve to permit the passage of exhaust gas therethrough. A series of interior closures () and annular baffles () may be provided to import a serpentine flow path to gases flowed through an exhaust pipe () containing a conformable catalyst member () therein. A mounting member () may be supplied to fasten one end of the conformable catalyst member () to the discharge end of an exhaust pipe ().
