摘要： A catalytic reactor for catalytic conversion of exhaust gases, in particular exhaust gases from internal combustion engines, includes a honeycomb body disposed in a metallic casing. The honeycomb body has a large number of channels through which exhaust gas can flow, a gas inlet side and a gas outlet side. The honeycomb body is thermally insulated by internal insulation over a part of its length from the gas inlet side onward and preferably also from the gas outlet side onward, with respect to an inner surface of the casing. An outer surface of the casing also has thermal insulation at least in some regions. The casing serves as a heat store or accumulator, at least in some regions. This construction provides advantageous properties during both cold starting and hot starting as one sub-region rapidly heats up during cold starting and one sub-region only slowly cools down after prolonged operation due to storage of heat in the casing.
