KATALYSATORSYSTEM FUER DIE ABGASBEHANDLUNG, VERFAHREN ZU SEINER HERSTELLUNG UND SEINE VERWENDUNG

摘要

A method is taught for increasing the selectivity of a catalyst in that the catalyst reduces the amount of ammonia produced when exhaust gases are catalytically treated to eliminate oxides of nitrogen therefrom. The method involves including molybdenum on the support media for the catalyst, in addition to the principal catalyst system present to effect the reduction of oxides of nitrogen.
