摘要： Disclosed is a catalyst system for the reduction of NOx. The catalyst system comprises a catalyst in a first zone comprising a catalyst support, a catalytic metal comprising gallium, and at least one promoting metal selected from the group consisting of silver, gold, vanadium, zinc, tin, bismuth, cobalt, molybdenum, tungsten, indium and mixtures thereof; a catalyst in the second zone following the first zone; the catalyst comprising a second catalyst support, a second catalytic metal selected from the group consisting of indium, copper, manganese, tungsten, molybdenum, titanium, vanadium, iron, cerium and mixtures thereof. The catalyst system further comprises a gas stream comprising an organic reductant comprising oxygen or nitrogen. The catalyst system may further optionally comprise a catalyst in a third zone following the second zone; the catalyst comprising a third catalyst support and a third catalytic metal selected from the group consisting of platinum, palladium, and mixtures thereof. A method for reducing NOx utilizing the catalyst system is also provided.
