A lean NOx trap (LNT) catalyst includes a plurality of carriers connected to each other in series, wherein each of the carriers is embedded with at least one of a first wash coat containing magnesium (Mg)-substituted alumina, ceria (CeO), barium (Ba), and a precious metal, a second wash coat containing magnesium (Mg)-substituted alumina, ceria (CeO), barium (Ba), a third wash coat containing magnesium (Mg)-substituted alumina, ceria (CeO), and a fourth wash coat containing magnesium (Mg)-substituted alumina, ceria (CeO), and a higher content of a precious metal than the first wash coat, a ratio of the magnesium-substituted alumina to ceria (CeO) being lower than that of the third wash coat, wherein the third and first wash coats are disposed in a foremost carrier through which exhaust gas passes sequentially from a front portion of the foremost carrier.

LNT catalyst

A method for controlling regeneration a catalyst by an exhaust gas purification device includes: measuring a temperature of exhaust gas flowing into a first catalyst unit; estimating a NOamount loaded into the first catalyst unit and a slip amount of NOof the first catalyst unit by using the temperature and an amount of the exhaust gas of the first catalyst unit; calculating a temperature of a second catalyst unit by using the temperature of the first catalyst unit; and estimating a NOamount flowing into the second catalyst unit by using at least one of the slip amount of NOof the first catalyst unit and the temperature of the second catalyst unit.

A catalyzed particulate filter that includes: at least one inlet channel extending in a longitudinal direction, one end of which lets fluid in, and the other end of which is blocked; at least one outlet channel extending in the longitudinal direction, one end of which is blocked and the other end of which lets the fluid out; at least one porous wall that defines the boundary between neighboring inlet and outlet channels and that extends in the longitudinal direction; and a support with a catalyst coating thereon.

Catalyzed particulate filter

Disclosed is a lean NOx trap (LNT) catalyst with enhanced NOx storage capacity at low temperature. More particularly, an LNT catalyst with enhanced NOx storage capacity at low temperature and significantly inhibited thermal desorption is prepared by coating a washcoat on a honeycomb-type carrier and drying and baking the same. The washcoat contains a first catalyst powder in which barium (Ba) and a precious metal are supported on a ceria support, and a second catalyst powder in which a precious metal is supported on a magnesium (Mg)-substituted alumina support The LNT catalyst of the present invention is useful as a NOx reducing catalyst for a passenger diesel vehicle.
