ABSTRACT:
A process for the catalytic reduction of nitrogen oxides (NOx) in a gas stream (29) in the presence of H2is provided. The process comprises contacting the gas stream with a catalyst system (38) comprising zirconia-silica washcoat particles (41), a pre-sulfated zirconia binder (44), and a catalyst combination (40) comprising palladium and at least one of rhodium, ruthenium, or a mixture of ruthenium and rhodium.
