摘要:
In the present invention, it is an assignment to optimize a loading density of noble metal on catalyst.Pt is loaded in such an amount that a loading amount per 1 liter of a support substrate exceeds 0.75 g on an exhaust-gas upstream side of a coating layer, and a loading density of Rh in the coating layer is made so that it becomes higher on an exhaust-gas downstream side than on the exhaust-gas upstream side. The purifying performance after warming up improves by loading Rh with high density on the exhaust-gas downstream side that is likely to become rich atmosphere.
摘要:
A regeneration apparatus comprises a heater 2 which heats a catalyst 1 at the time of stopping fuel supply to an engine, a pump 4 which supplies an oxidizing gas or a reducing gas to the heated catalyst 1 and a switching valve 3. In the oxidizing step, catalytic poisons, for example hydrocarbon, which are absorbed on a noble metal are oxidized and removed. The particles of the noble metal become oxidized particles as pure oxide and the like. After the oxidizing step, the reducing step is carried out. In the reducing step, particles of the noble metal are reduced and re-dispersed on the support simultaneously and as a result, the particles of the noble metal become fine. Thus, a deteriorated catalyst can be regenerated without interrupting the use of catalyst and also without deteriorating the drivability.

摘要:
To improve a CO conversion in stoichiometry-lean atmosphere, and additionally to prevent the rise of pressure loss.A catalytic coating layer 2 is constituted of a lower layer 20 including an oxygen storage capacity material and an upper layer being formed on a surface of the lower layer 20 and including a catalytic noble metal, and a thickness of the upper layer is adapted so as to be 5 μm-40 μm. The upper layer 21 is good in terms of gas diffusibility, and thereby OSC resulting from the oxygen storage capacity material being included in the lower layer 20 is demonstrated maximally.
