An oxidation catalyst composite, methods, and systems for the treatment of exhaust gas emissions from a diesel engine are described. More particularly, an oxidation catalyst composite including a first washcoat comprising a zeolite, Pt, and first refractory metal oxide support containing manganese, a second washcoat comprising a second refractory metal oxide support, a Pt component and a Pd component, and a third washcoat comprising palladium and a rare earth oxide component is described.

A nitrous oxide (NO) removal catalyst composite is provided, comprising a NO removal catalytic material on a substrate, the catalytic material comprising a rhodium (Rh) component supported on a ceria-based support, wherein the catalyst composite has a H-consumption peak of about 100&#xb0; C. or less as measured by hydrogen temperature-programmed reduction (H-TPR). Methods of making and using the same are also provided.

Nitrous oxide removal catalysts for exhaust systems

The present invention provides an oxidation catalyst composition suitable for at least partial conversion of gaseous hydrocarbon emissions, e.g., methane. The oxidation catalyst composition includes at least one platinum group metal (PGM) component supported onto a porous zirconia-containing material that provides an effect on hydrocarbon conversion activity. The porous zirconia-containing material is at least 90% by weight in the monoclinic phase. Furthermore, the PGM component can comprise at least one platinum group metal in the form of colloidally deposited nanoparticles. The oxidation catalyst composition can be used in the treatment of emissions from lean compressed natural gas engines.

Oxidation catalyst for lean compressed natural gas engine

The present invention relates to a selective catalytic reduction catalyst for the treatment of an exhaust gas of a diesel engine comprising: a flow-through substrate comprising an inlet end, an outlet end, a substrate axial length extending from the inlet end to the outlet end and a plurality of passages defined by internal walls of the flow through substrate extending therethrough; a coating disposed on the surface of the internal walls of the substrate, wherein the coating comprises a non-zeolitic oxidic material comprising manganese and one or more of the metals of the groups 4 to 11 and 13 of the periodic table, and further comprises one or more of a vanadium oxide and a zeolitic material comprising one or more of copper and iron.

Selective catalytic reduction catalyst for the treatment of an exhaust gas of a diesel engine

The present disclosure generally provides low-temperature nitrogen oxides (NO) adsorbers used in the treatment of a NO-containing exhaust gas stream and to methods of preparing and using the same. In particular, the NOadsorber composition includes an active metal and a metal oxide support, wherein the metal oxide support includes greater than 50% by weight ceria based on the total weight of the NOadsorber composition, and wherein the active metal includes about 0.01% to about 5% by weight ruthenium based on the total weight of the NOadsorber composition.

Ruthenium impregnated ceria catalyst

Composites of mixed metal oxides for an exhaust gas purifying catalyst comprise the following co-precipitated materials by weight of the composite: zirconia in an amount in the range of 55-99%; titania in an amount in the range of 1-25%; a promoter and/or a stabilizer in an amount in the range of 0-20%. These composites are effective as supports for platinum group metals (PGMs), in particular rhodium.

A nitrous oxide (NO) removal catalyst composite is described, which includes: a NO removal catalytic material on a carrier, wherein the catalytic material comprises a platinum group metal (PGM) component on a ceria-containing support having a single phase, cubic fluorite crystal structure. The catalytic material is effective to decompose nitrous oxide (NO) to nitrogen (N) and oxygen (O) and/or to reduce NO to Nand water (HO) and/or (CO) under conditions of an exhaust stream of an internal combustion engine operating under conditions that are stoichiometric or lean with periodic rich transient excursions. Methods of making and using the same are also provided.
