Abstract: Catalyzed particulate filters comprise three-way conversion (TWC) catalytic material, which comprises rhodium as the only platinum group metal, that permeates walls of a particulate filter. Such catalyzed particulate filters may be located downstream of close-coupled three-way conversion (TWC) composites in an emission treatment system downstream of a gasoline direct injection engine for treatment of an exhaust stream comprising hydrocarbons, carbon monoxide, nitrogen oxides, and particulates.

Abstract: The invention provides an emission control system for treatment of an exhaust gas stream of an engine, including an engine producing an exhaust gas stream; an SCR catalyst unit downstream from the engine and in fluid communication with the exhaust gas stream; and an ammonia generation system comprising a reservoir containing ammonium hydroxide and an ammonia injector, wherein the reservoir is in fluid communication with the ammonia injector and the ammonia injector is in fluid communication with the exhaust gas stream upstream of the SCR catalyst unit. A method of treating an exhaust gas stream of an engine is also provided, including the steps of heating ammonium hydroxide to produce gaseous ammonia and transferring the gaseous ammonia through an ammonia injector into the exhaust gas stream such that the gaseous ammonia disperses within the exhaust gas stream upstream of a SCR catalyst unit.

Abstract: The present disclosure relates to copper-containing molecular sieve catalysts that are highly suitable for the treatment of exhaust containing NOx pollutants. The copper-containing molecular sieve catalysts contain ion-exchanged copper as Cu+2 and Cu(OH)+1, and DRIFT spectroscopy of the catalyst exhibits perturbed T-O-T vibrational peaks corresponding to the Cu+2 and Cu(OH)+1. In spectra taken of the catalytic materials, a ratio of the Cu+2 to the Cu(OH)+1 peak integration areas preferably can be ≥1. The copper-containing molecular sieve catalysts are aging stable such that the peak integration area percentage of the Cu+2 peak (area Cu+2/(area Cu+2+area Cu(OH)+1)) increases by ≤20% upon aging at 800° C. for 16 hours in the presence of 10% H2O/air, compared to the fresh state.
