摘要： The present invention relates to a layered catalyst composite of the type generally referred to as a three-way conversion catalyst having the capability of simultaneously catalyzing the oxidation of hydrocarbons and carbon monoxide and the reduction of nitrogen oxides. The structure of the layered catalyst composite of the present invention is designed wherein there are three layers in conjunction with a carrier: a first layer deposited on the carrier and comprising a high surface area refractory metal oxide; a second layer deposited on the first layer and comprising palladium and/or platinum deposited on a high surface area refractory metal oxide, and having substantially no oxygen storage components; and a third layer deposited on the second layer and comprising platinum and/or rhodium as well as an oxygen storage component, deposited on a high surface area refractory metal oxide.

摘要： Provided is an exhaust article (catalyst) coated on a single substrate, such as a monolithic honeycomb having a plurality of channels along the axial length of the catalyst. Different washcoat compositions are deposited along the length the channel walls of the substrate beginning from either the inlet or outlet axial end of the substrate to form inlet and outlet catalyst layers, respectively. In the coating process, the channel walls are coated with catalyst washcoat compositions to lengths that are less than the substrates' axial length. The architecture of the resulting catalyst layers defines a plurality of zones along the length of the substrate. The properties of each zone of the catalyst can be optimized to address specific catalyst functions by manipulation of both the coating lengths and the catalyst washcoat compositions.

摘要： A novel catalytic material is prepared by dispersing a catalytically active species, e.g., one or more platinum group metals, on a support phase that contains a high porosity, meso-pores high surface area (HPMPHSA) material. The HPMPHSA material has a porosity, measured in millilitres per gram of material, that is typically at least about 30 percent greater than that of a corresponding conventional material, preferably at least 50 percent greater. In a particular embodiment, the support phase of the catalytic material contains a HPMPHSA alumina having porosity of about 0.9ml/g, whereas a conventional alumina typically has a porosity of about 0.45 ml/g. The surface area is above 90, preferably above 100, more preferably equal or above 150 to 160 m /g. The support phase may be wholly composed of the HPMPHSA material or it may be composed of a mixture of the HPMPHSA material and a conventional material. Such a mixture preferably contains at least about 20 percent HPMPHSA material, by weight, e.g., 20 to 50 percent by weight.

摘要： Hydrogen sulfide formation is suppressed by a three-way conversion catalyst having an underlayer and a topcoat overlying the under layer. The under layer is prepared by dispersing a Group IIa metal oxide such as an oxide of magnesium, calcium, barium or strontium on a carrier such as a refractory metal oxide monolith. A topcoat overlying the undercoat is comprised of a three-way conversion catalyst material such as a platinum-group metal catalytic component, e.g., platinum, palladium, rhodium or mixtures thereof.
