Abstract:
A poison-resistant catalytic converter includes a washcoat having a support material comprised of titania and/or silica and a plurality of platinum group metal particles disposed in the support material. The washcoat is disposed on a substrate having a plurality of cells that define respective apertures. The catalytic converter is resistant to poisoning from sulfur and phosphorous compounds while operating at low temperatures. Applications include spark ignited internal combustion engines in combined heat and power systems, vehicles, combustion turbines, boilers and other applications for utilities, industry and vehicle emissions control.

Claim (Index 11):
A system for treating exhaust generated by a rich burn spark-ignited internal combustion engine, the system comprising:\n a first-stage catalyst chamber including a first three-way catalyst (TWC), the first-stage catalyst chamber in fluid communication with an exhaust outlet of the engine, the first stage catalyst chamber removing at least a portion of at least one of a NOx, a CO, or a hydrocarbon content in the exhaust to form a first output exhaust; a cooling apparatus in fluid communication with an outlet of the first-stage catalyst chamber, the cooling apparatus configured to cool the first output exhaust to 300\u00b0 F.-650\u00b0 F., the cooling apparatus outputting a cooled exhaust; an air injector in fluid communication with a conduit extending from an outlet of the cooling apparatus, the air injector configured to increase an oxygen content of the cooled exhaust to 0.25%-2.0% by volume; a second-stage catalyst chamber including a poison-resistant catalyst, the second-stage catalyst chamber in fluid communication with the conduit to receive the cooled and oxygenated exhaust, the poison-resistant catalyst includes the catalytic converter of  claim 1 , wherein the second-stage catalyst chamber removes at least a portion of a CO content and a hydrocarbon content of the cooled exhaust.
