    摘要： A catalyst which purges a diesel engine exhaust gas of HC, CO, and SOF and reduces the emission of particulates as well and a method for the production thereof are provided. The catalyst for purifying a diesel engine exhaust gas has deposited on a refractory three-dimensionalstructure a catalyst component comprising silica-alumina supporting at least one noble metal selected from the group consisting of platinum, palladium, and rhodium and zeolite. This catalyst is produced by adding a noble metal component into a slurry of silica-alumina thereby inducing chemical adsorption, then adding zeolite to the resultant mixture thereby obtaining a mixed slurry of a noble metal-supporting silica-alumina and zeolite, dipping a refractory three-dimensional structure in the slurry thereby inducing deposition of the catalyst component, and subsequently calcining the resultant composite.

    摘要： A method and a device for controlling an exhaust emission from an internal combustion engine excellent also in the removal of particulates from the exhaust emission exhausted from the internal combustion engine, particularly a diesel engine. The method uses the exhaust emission control device comprising an oxidation area in which an oxidation catalyst carrying both platinum and palladium along the flow of the exhaust emission is installed in the exhaust passage of the internal combustion engine and a filtrating area in which a particulate filter is installed. The method and device are characterized in that a hydrocarbon-based liquid is supplied to the exhaust emission inflow side of the oxidation area when the particulates of 2 to 10 g per liter of the particulate filter are collected, and the exhaust emission is heated to a temperature of 550 °C or higher by the oxidation catalyst to burn residue in the particulate filter.
