Abstract: A method of forming an improved material having a matrix of oxidized, high surface area, uniformly dispersed active and carrier materials that is useful, not only as a catalyst, but also as an adsorbent for adsorbing a high concentration of contaminants, such as arsenic and selenium, deeply within its matrix and still retain its structural integrity characterized by the steps of preparing a single solution containing uniformly distributed water-soluble salts of the active and carrier cations; reacting them with a basic solution, such as ammonium hydroxide, to form insoluble and uniformly dispersed coprecipitates; drying the co-precipitates; removing the undesirable by-product; comminuting dried co-precipitates; forming the comminuted co-precipitates into an aqueous slurry; forming the slurry into particles of the desired size and shape; drying the particles; and calcining in an oxidizing atmosphere the dried particles to incorporate oxygen atoms into the matrix to achieve the requisite co-precipitated material, hardness and surface area. Also disclosed are preferred additional method steps, compositions and uses.

Abstract: Catalysts for the oxidative purification of exhaust gases such as the exhaust gases from internal combustion engines, are prepared by applying a suspension whose solid content consists essentially of boehmite to a ceramic support body thereby forming an intermediate coating which is adapted to receive one or more metals of the platinum group or alloys thereof in finely divided form. The thus treated support body is thereafter heated. The coating suspension also can contain dissolved aluminum nitrate. The intermediate coating of boehmite on the support body is converted to active aluminum oxide prior to impregnation with one or more metals of the platinum group or alloys thereof in finely divided form or the conversion can take place after such impregnation, for example, by heating upon exposure to the hot exhaust gases of an internal combustion engine.

Abstract: 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.

Abstract: A highly active, stable and sulfur-resistant catalyst composition useful for substantially reducing the amount of carbon monoxide, hydrocarbons, nitrogen oxide and other noxious components in a gaseous stream is provided. Said catalyst composition comprises a specific refractory support material selected from the group consisting of (1) an alumina having a particle density of from about 0.3 to about 1.5 g/cc, a packed density of from about 0.2 to about 0.8 g/cc and a surface area of from about 10 to about 300 m2/g and (2) a monolithic ceramic having an external surface area of from about 100 to about 900 ft2/ft3, a bulk density of from about 10 to about 50 lb/ft3 and from about 2 to about 500 channels per square inch, said refractory support material having deposited thereon from about 0.01 to about 10 weight percent palladium and from about 0.05 to about 20 weight percent metal selected from the group consisting of rare earth, iron, manganese and zinc. The catalyst composition of this invention is effective at lower catalyst bed temperatures than other similar compositions, thus making it valuable when said gaseous stream is the exhaust effluent of an internal combustion engine during low-temperature operation, e.g. engine start-up. The catalyst composition also has excellent stability to aging in internal combustion engine exhaust effluent, even when the fuel to said engine contains up to 1000 ppm sulfur.
