The invention relates to chemical removal of oxides of nitrogen (NOx) from gases which contain sulfuric compounds, in particular, the oxides of sulfur (SOx), with the use of a catalyst. A poison-resistant catalyst for reduction of oxides of nitrogen with hydrocarbons in oxidizing atmosphere on the basis of zeolite contains metal ions. A cation-decationized form of pentasil or synthetic or natural mordenite, in which the hydrogen ions for 10-43% are substituted for the ions of alkaline earth metals or the ions of magnesium is used, as zeolite.
