ABSTRACT:
A low-cost catalytic article is provided for treating gaseous fluid streams such as exhaust streams from gasoline-powered engines. The articles contain residence chambers defined by chamber walls and foraminous catalytic elements that contain a catalyst composition for converting a reactant contained in the fluid stream, and deflectors, which increase the residence time of the fluid stream in the residence chamber and the contact time of the fluid stream with the catalytic element.
