    摘要： The present invention is directed to an improved apparatus and method of minimizing catalyst poisoning from exhaust gas streams containing inorganic deposits and particulate matter. More specifically, the present invention is directed to an upstream metallic foam trap and a downstream monolithic precious metal catalyst, wherein the trap physically blocks inorganic deposits and particulate matter from poisoning the downstream catalyst. The present invention is also directed to a metallic foam trap containing a coat comprising a first metallic thermal arc sprayed layer and optionally a second refractory metal oxide.

    摘要： Provided is an emissions treatment system and method for reducing NOx emissions in the exhaust stream produced from an internal combustion engine. The system has an injector for periodically metering ammonia or an ammonia precursor into an exhaust stream; and a first substrate with a first SCR catalyst composition, downstream of the injector. The first substrate has an inlet end, an outlet end, a length extending between the inlet end to the outlet end, and wall elements. The first SCR catalyst composition is disposed on the wall elements from the inlet end toward the outlet end to form an inlet zone. The first substrate also has an NH3 destruction catalyst composition with a platinum group metal component dispersed on a refractory metal oxide. The NH3 destruction catalyst is disposed on the wall elements from the outlet end to form an outlet zone.

    摘要： Provided is an emissions treatment system and method for reducing NOx emissions in the exhaust stream produced from an internal combustion engine. The system has an injector for periodically metering ammonia or an ammonia precursor into an exhaust stream; and a first substrate with a first SCR catalyst composition, downstream of the injector. The first substrate has an inlet end, an outlet end, a length extending between the inlet end to the outlet end, wall elements and a plurality of passages defined by the wall elements. The first SCR catalyst composition is disposed on the wall elements from the inlet end toward the outlet end to a length that is less than the substrate's axial length to form an inlet zone.The first substrate also has an NH3 destruction catalyst composition with a platinum group metal component dispersed on a refractory metal oxide. The NH3 destruction catalyst is disposed on the wall elements from the outlet end toward the inlet end to a length that is less than the substrate's axial length to form an outlet zone. Generally, there is from 0.1 to 10 g/ft3 of platinum group metal component in the outlet zone.
