A catalytic reactor for an internal combustion engine having a cooling jacket surrounding multiple catalyst elements. A thermal barrier layer is formed between the catalyst elements and the cooling jacket to prevent over cooling of the catalyst elements. The thermal barrier layer can be formed from insulating elements such as fibrous material, a plurality of annular rings disposed around the catalyst elements, a corrugated layer, or can be formed by an empty space.

[ What is claimed is:] [1.] A catalytic reactor system comprising:an inner cooling jacket and an outer cooling jacket;a catalyst element disposed within said inner cooling jacket;a first end adapted to be connected to an exhaust conduit from an internal combustion engine for receiving an exhaust gas and a second end adapted to be connected to a conduit for passing the exhaust gas after contact with said catalyst element;a cooling passageway between said outer cooling jacket and said catalyst element, said cooling passageway comprising a cooling air inlet;a thermal insulative space between said inner cooling jacket and said outer cooling jacket; anda thermal insulative material disposed in said insulative space, said thermal insulative material being semi-elastic, generally restrictive to exhaust gas flow and supportive of said catalyst element.
