Abstract
A ceramic honeycomb catalytic converter having a novel canning structure capable of stably retaining a thin-walled ceramic honeycomb catalyst within a metal casing for a long period. A retainer member in the form of a ceramic fiber mat is disposed between an inner peripheral surface of the casing and an outer peripheral surface of the honeycomb catalyst, in a compressed state to generate a surface pressure for retaining the honeycomb catalyst in place. The ceramic fiber mat is composed of heat resistant and non-intumescent ceramic fibers, and has a compression characteristic which is substantially free from a significant increase or decrease over an operative temperature range of the catalytic converter. The casing may be provided with at least one locking member for locking the ceramic fiber mat in a flow direction of exhaust gas passed through the honeycomb catalyst.
