ABSTRACT:
This invention provides a material for a catalyzer for purifying the exhaust gas using metallic carrier and the catalyzer using said material. The material for the catalyzer is formed by providing a plurality of tabs protruding from one side surface or either side surfaces of a heat-resisting metallic thin plate such as made of a heat-resisting ferritic stainless steel. The catalyzer is formed by winding spirally or bending in the zig-zag form the material for the catalyzer solely or in combination with another metallic plane plate so as to be formed in the desired size and shape. The exhaust gas flowing through the space between the opposing portions of the metallic thin plate is rendered to be turbulent flow by virtue of the provision of the tabs thereby insuring the time necessary for receiving the heat from the exhaust gas to be obtained, while the temperature of the catalyzer can be quickly raised by virtue of the shape of the tips of the tabs tending to be easily heated so that the time required for the activation of the catalyzer can be constructed.
