CATALYST SYSTEM AND METHOD FOR THE REDUCTION OF NOX

摘要

A catalyst system for the reduction of NOx comprises a catalyst comprising a metal oxide catalyst support, a catalytic metal oxide comprising at least on e 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 NOx utilizing the said catalyst system is also provided.
