摘要： A catalyst converter of the type employing a radial flow catalyst substrate. First and second enclosing can sections define an interior volume sufficiently large to have the radial flow catalyst substrate supported therewithin. Structure is provided for blocking one end of the radial flow catalyst substrate and additional structure is provided for mounting the blocking structure in contact with one end of the catalyst substrate. Support and sealing structures are provided at opposite ends of the enclosed catalyst substrate in order to resiliently cushion the substrate. The structure permits exhaust gases to flow into the interior volume of the catalyst substrate, radially through the substrate and then out to an exhaust pipe. The substrate has catalytically active material thereon for eliminating undesirable components of the gas stream passing through the converter.

摘要： A process is taught for producing a ruthenium catalyst. A ruthenate is presynthesized, ground into a fine powder, dispersed in a gamma alumina containing medium and applied as a slurry to a catalytic support. The ruthenate slurry is dried on the support and calcined. The product produced in this manner is desirable for use in the catalytic conversion in a reducing atmosphere of oxides of nitrogen. The ruthenium catalyst of the product produced by this method is resistant to volitalization when exposed to an oxidizing ambient.

摘要： A catalyst construction and method of making is disclosed for treating automotive exhaust gases from a fossil fueled internal combustion engine. The construction comprises: (a) a substrate; (b) a coating on said substrate having comingled first and second phases, said first phase comprising ceria and precious metal in microscale intimacy and said second phase comprising precious metal substantially devoid of ceria and separated from the ceria in said first phase on a macroscale. The phases may be in particle form with (i) the first phase particles resulting from the codeposition of CeO2, precious metal, and Al2O3 from an aqueous solution containing dissolved salts of CeO2 and precious metal and suspended particles of Al2O3; and (ii) the second phase particles resulting from the codeposition of precious metal and Al2O3 from an aqueous solution containing a dissolved salt of the precious metal and suspended particles of Al2O3. Alternatively, the substrate has Al2O3 thereon to increase its surface area, and the two-phase coating is adhered to said Al2O3, said first phase resulting partially from the discontinuous deposition of CeO2 onto said Al2O3 and partially from the continuous deposition of precious metal over said discontinuous CeO2 and over the exposed Al2O3; the precious metal in immediate microscale contact with the CeO2 constitutes the first phase and the precious metal not immediately in microscale contact with the CeO2 constitutes the second phase.
