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.
