Abstract: A catalytic converter having contained and disposed in the outlet plenum thereof a fusible material operative to absorb a portion of the sensible heat of the treated exhaust gases passing out of the converter during periods of converter operation and to release a portion of the absorbed heat to the catalytic element during periods of non-operation to maintain the temperature of the catalytic element above its minimum activation temperature for prolonged periods of non-operation. In the preferred embodiment, the fusible material consists of a zinc chloridesodium chloride eutectic.
