Multi-zoned catalytic trap and methods of making and using the same |
| abstract |
It provides a multi-band catalyst trap for the conversion of NO x in the exhaust gas stream emitted from the engine running periodically alternating between lean and stoichiometric or rich conditions. The catalyst trap includes a first zone, a second zone, and optionally one or more intermediate zones disposed between the first zone and the second zone. Each zone includes a catalyst trap material coated on a refractory carrier member. In the first zone, the catalyst trap material comprises a palladium catalyst component in an amount of about 30 to about 300 g / ft 3 (about 0.85 to about 8.50 g / m 3 ) and a platinum catalyst component of 0 to about 100 g / ft 3 ( Refractory metal oxide support dispersed thereon in an amount of from 0.00 to about 2.83 g / m 3 ) and in an amount of from 0 to about 10 g / ft 3 (0.00 to about 0.28 g / m 3 ); And one or one type of at least one basic oxygenated compound and the alkali metal optionally at least one or more kinds of alkaline earth metal including the NO X absorbent comprising a basic oxygenated compound. In the second zone, the catalyst trap material comprises a palladium catalyst component in an amount of 0 to about 50 g / ft 3 (0.00 to about 1.42 g / m 3 ) and a platinum catalyst component of about 10 to about 100 g / ft 3 (about Refractory metal oxide support dispersed thereon in an amount of 0.28 to about 2.83 g / m 3 ) and in an amount of about 5 to about 20 g / ft 3 (about 0.14 to about 0.57 g / m 3 ); And an NO X adsorbent comprising at least one basic oxygenated compound of at least one metal selected from the group consisting of alkali metals and alkaline earth metals. In an optional zone (s), the catalyst trap material may comprise a palladium catalyst component in an amount of about 25 to about 75 g / ft 3 (about 0.71 to about 2.12 g / m 3 ) and about 5 to about 30 g of platinum catalyst component. refractory metal oxide dispersed thereon in an amount of / ft 3 (about 0.14 to about 0.85 g / m 3 ) and the rhodium catalyst component in an amount of 0 to about 10 g / ft 3 (0.00 to about 0.28 g / m 3 ) Support; And an NO X adsorbent comprising at least one basic oxygenated compound of at least one metal selected from the group consisting of alkali metals and alkaline earth metals. |
