Reactor containing a resiliently supported catalyst carrier body for the detoxification of exhaust gases of internal combustion engines

Claim 1

IN A CATALYTIC REACTOR FOR THE DETOXIFICATION OF EXHAUST GASES OF INTERNAL COMBUSTION ENGINES, SAID REACTOR INCLUDING A REACTOR CASING WITHIN WHICH A MONOLITHIC CATALYST CARRIER BODY IS RESILIENTLY AND SUBSTANTIALLY AXIALLY SUPPORTED IN A SPACED RELATIONSHIP TO THE INNER WALL OF SAID CASING AND WHEREIN SAID BODY HAS A LARGE SURFACE AREA AND INCLUDES A PLURALITY OF FLOW CHANNELS FOR SAID EXHAUST GASES, SAID LARGE SURFACE AREA HAVING DEPOSITED THEREON A CATALYST MATERIAL, AND WHEREIN A PROTECTIVE JACKET IS PROVIDED AROUND THE CARRIER BODY PROPER SAID JACKET EXTENDING AT LEAST AROUND THE CIRCUMFERENTIAL SURFACE OF THE CATALYST CARRIER BODY PROPER AND BEING LOCATED BETWEEN SAID BODY AND SAID INNER WALL OF SAID CASING AND SPANNING THE ANNULAR SPACE THEREBETWEEN, THE IMPROVEMENT WHEREIN SAID PROTECTIVE JACKET COMPRISES AN EVELOPE OF HEAT INSULATING FIREPROOF CERAMIC FIBERS, HEAT RESISTANT STEEL REINFORCEMENT MEANS LOCATED IN SAID ENVELOPE, AND A HEAT RESISTANT BINDER MORTAR IN WHICH SAID CERAMIC FIBERS AND SAID REINFORCEMENT MEANS ARE EMBEDDED, WHEREBY THE STEEL REINFORCEMENT MEANS PROVIDE THE NECESSARY STURDINESS, WHEREAS THE CERAMIC FIBERS PROVIDE THE REQUIRE ELASTICITY.
