摘要： To provide a method for industrially efficiently producing an exhaust gas purifying catalyst containing a perovskite-type composite oxide which is stable and has a less reduced specific surface area and is also effectively prevented from decreasing in its catalytic performance even in endurance in high temperature oxidative reducing atmospheres, a pre-crystallization composition containing elementary components constituting a perovskite-type composite oxide containing a noble metal is prepared, is mixed with a powder of theta-alumina and/or alpha-alumina to prepare a mixture, and the mixture is heat treated. Thus, the resulting perovskite-type composite oxide supported by the powder of theta-alumina and/or alpha-alumina can keep its thermostability at a sufficient level thereby to effectively prevent the catalytic performance from decreasing. This method can industrially efficiently produce the exhaust gas purifying catalyst.

摘要： PROBLEM TO BE SOLVED: To reduce a fuel consumption required for forcibly regenerating a PM filter.
SOLUTION: An exhaust emission control device comprises an oxidation catalyst 20 and a PM filter catalyst 30 disposed on an exhaust gas downstream side of the oxidation catalyst 20 for collecting particulates in exhaust gas. The oxidation catalyst 20 has a plurality of straight cells 21 in which the exhaust gas directly flows, straight cell partition walls 22 separating the straight cells 21 from each other, oxidation catalytic layers formed on the surfaces of the straight cell partition walls 22 and partially closed parts 24 serving as the collection parts of a construction capable of collecting a part of the PM in the exhaust gas passing through the straight cells 21. When fuel of a high temperature of about 600°C or more is supplied to the oxidation catalyst 20 in forcibly regenerating the PM filter catalyst 30, the PM accumulated in the partially closed parts 24 is burned and generates heat and this heat can be used for regeneration of the PM filter.
