摘要： Apparatus adapted to receive one or more catalysts for the decontamination of exhaust gas of internal combustion engines. The apparatus, which includes a closed container for one or more beds of catalyst, is provided with an inlet for introducing exhaust gas thereinto and with an outlet for removing decontaminated exhaust gas therefrom. The catalyst beds are maintained in position by means of a spring-actuated clamping device which comprises a thrust rod, a mounting therefor and a spring element. The spring element, which bears against the mounting, urges the thrust rod into close contact with the catalyst beds.

摘要： A carrier-supported catalyst is made by impregnating a ceramic honeycomb structure having a layer of a heat resistant metal oxide applied to it with the aqueous solution of at least one metal selected from platinum, rhodium and palladium, drying the impregnated honeycomb structure and annealing it. More particularly a drying gas regularly distributed across the entire cross-sectional area of the impregnated honeycomb structure is passed therethrough at 20.degree. to 400.degree. C. The temperature and quantity of drying gas are selected so that water ceases to be evaporated from the impregnated honeycomb structure after 30 to 300 seconds and the dried impregnated honeycomb structure is heat-treated over a period of 1 to 3 hours at temperatures up to 1000.degree. C.
