摘要： A lean NOx trap composition for the treatment of exhaust gas emissions, such as the oxidation of unburned hydrocarbons (HC), and carbon monoxide (CO), and the trapping and reduction of nitrogen oxides (NOx) is disclosed. The lean NOx trap composition can have a washcoat layer on a carrier substrate including a first support material comprising greater than 50% by weight of a reducible metal oxide; 10 to 30% by weight of alkaline earth metal supported on a second support material comprising a refractory metal oxide and 50% or less by weight of a reducible metal oxide and; and a platinum group metal component supported on at least one of the first support material and/or the second support material. A portion of the first support material may further include 0.5% to 10% by weight of an alkaline earth metal.

摘要： The present disclosure is directed to an emission treatment system for oxidation of hydrocarbons and carbon monoxide and for NOx abatement in an exhaust stream of a lean burn engine, the emission treatment system including a low-temperature NOx adsorber (LT-NA) that includes a molecular sieve impregnated with at least one PGM component positioned in fluid communication with the exhaust stream; and an oxidation catalyst that includes a refractory metal oxide support containing manganese impregnated with platinum positioned in fluid communication with the exhaust stream, each of the LT-NA and the oxidation catalyst being disposed on a substrate. The invention provides a catalyst article combining an oxidation catalyst with a LT-NA and a related method of treatment of an exhaust gas.
