Abstract
FIELD: gas purification. SUBSTANCE: invention relates to removing nitrogen oxides from both dry and wet as well as sulfur-containing effluent gases by way of reducing with hydrocarbons using zeolite-based catalysts not containing precious metals. Zeolites of catalysts containing transition metal cations are additionally modified with strontium or zinc. High degree of purification is achieved under drastic conditions with volume velocities of gases to be treated up to 120000 hand also under rather low temperatures. EFFECT: facilitated removal of nitrogen oxides. 2 tbl
