ABSTRACT:
A catalyst system for the reduction of NOxcomprises a catalyst comprising a metal oxide catalyst support, a catalytic metal oxide comprising at least one of gallium oxide or silver oxide, and at least one promoting metal selected from the group consisting of silver, cobalt, molybdenum, tungsten, indium, bismuth and mixtures thereof. The catalyst system further comprises a gas stream comprising an organic reductant, and a compound comprising sulfur. A method for reducing NOxutilizing the said catalyst system is also provided.
