A method for reducing the gas leakage avoidance in a catalytic converter with a ceramic monolithic catalytic converter element and converter for carrying out the method

摘要

Arrangement for resiliently mounting a ceramic monolithic type catalytic converter element in a metal housing with a blanket of knit wire mesh material includes at least one circumferential band of high temperature intumescent material containing ceramic fibers positioned within the wire mesh blanket which prevents virtually all bypass leakage around the element and substantially reduces the temperature of the wire mesh.
