The present disclosure is directed to an emission treatment system for oxidation of hydrocarbons and carbon monoxide and for NOabatement in an exhaust stream of a lean burn engine, the emission treatment system including a low-temperature NOadsorber (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.

Coordinated emission control system including diesel oxidation catalyst and low temperature NOadsorber

The present invention relates a system for the treatment of an exhaust gas of a diesel combustion engine, said system comprising a specific NOx adsorber component, a diesel oxidation catalyst (DOC) component, a selective catalytic reduction (SCR) component, a gas heating component, and a reductant injector, wherein in said system, the specific NOx adsorber component is arranged upstream of the gas heating component, the reductant injector is arranged up-stream of the SCR component, the gas heating component is arranged upstream of the reductant injector, the DOC component is arranged upstream of the reductant injector, and the DOC component and the gas heating component are directly consecutive components. Further, the present invention relates a process for preparing such a system and use thereof.

Catalytic system for the treatment of an exhaust gas of a combustion engine

The present disclosure is directed to a method for treating a gaseous exhaust stream containing nitrogen oxides (NO) from a diesel or lean-burn gasoline engine following a cold-start of the engine The method involves contact of the gaseous exhaust stream with at least a low temperature NOadsorber (LT-NA) component. The LT-NA component includes a rare earth metal component, a platinum group metal (PGM) component, and a dopant. The present disclosure is also directed to a method of modulating a NOadsorption/desorption profile of an LT-NA composition, a NOdesorption temperature range of an LT-NA composition, or both.
