Abstract: In one embodiment, a method for making a catalytic element comprises forming a first slurry of a promoter oxide precursor and a refractory inorganic oxide and calcining the first slurry to form a supported promoter. The supported promoter and a noble metal solution are combined to form a second slurry that is calcined to form a catalyst composition. The catalyst composition is applied to a substrate and the substrate is calcined to form the catalytic element. In one embodiment, the catalyzed particulate filter comprises a shell disposed around the catalytic element, wherein the shell has an inlet and an outlet, and a retention member disposed between at least a portion of the shell and the catalytic element.

Abstract: A honeycomb body, particularly a catalyst carrier body that serves to clean an exhaust gas of an internal combustion engine, includes a honeycomb structure joined to a casing tube by a joining techniques. The honeycomb structure is at least partially surrounded by an inner sleeve and at least partially by an outer sleeve. The inner sleeve and the outer sleeve are placed in an axial section between the casing tube and the honeycomb structure. The adjacently disposed components are joined to one another by a plurality of joining locations, and an open spring-damper system is formed by at least one sleeve. A long-life system for fixing a honeycomb structure in a casing tube is thus provided which permits thermal compensating expansions and distinctly reduces the tendency of the honeycomb structure to vibrate with regard to the casing tube. A method for producing such a honeycomb body is also provided.

Abstract: 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.

Abstract: An exhaust gas purifying system and a catalyst used for the system prevents NOx absorbent from being poisoned by a sulfur compound to keep NOx absorption performance. The catalyst has at least an inner and an outer layer on a support material, the inner layer having NOx absorbent capable of absorbing NOx and a sulfur compound in the exhaust gas produced from combustion of a lean fuel mixture, releasing the NOx into the exhaust gas and substantially stopping absorbing the sulfur compound when a rich mixture is burnt, and the outer layer having a sulfur compound absorbent capable of absorbing the sulfur compound in the exhaust gas produced from combustion of a lean fuel mixture and capable of discharging the sulfur compound into the exhaust gas when a rich fuel mixture is burnt while the engine operates in a lean-burn zone. NOx is absorbed by the NOx absorbent in the inner layer and the sulfur compound is adsorbed in the sulfur compound absorbent in the outer layer. Therefor the NOx absorbent in the inner layer is protected from being poisoned by the sulfur compound.

Abstract: A metal catalyst carrier has a core comprising a corrugated sheet and a flat sheet with a plurality of slots in a shape elongated in a direction perpendicular to a cell passage direction. The slots are formed before a sheet metal is corrugated and have a predetermined interval apart from one another. The plural slots disposed along the direction perpendicular to the cell passage direction are arranged to form a plurality of slot arrays arranged in the cell passage direction, and an interval Y in the cell passage direction and an interval X in the direction perpendicular to the cell passage direction, between the opening peripheral edge portions of the slots adjacent to each other in the slot arrays adjacent to each other, are set under the conditions satisfying Xnull0 mm and Xnullnull(5/2)Ynull10 mm, thereby preventing the occurrence of distortions and cracks in the process of corrugating the sheet metal.
