Title:
ディーゼルエンジン排ガス浄化用触媒およびその製造方法
Document Type and Number:
Japanese Patent JP4210552
Kind Code:
B2
Abstract:
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.
