Abstract
A process and system () for reducing NOin a gas using hydrogen as a reducing agent is provided. The process comprises contacting the gas stream () with a catalyst system () comprising sulfated zirconia washcoat particles (), palladium, a pre-sulfated zirconia binder (), and a promoter () comprising at least one of titanium, zinc, or a mixture thereof. The presence of zinc or titanium increases the resistance of the catalyst system to a sulfur and water-containing gas stream.
