FIELD: process engineering.
SUBSTANCE: invention relates to catalyst, methods of its production and application for cleaning off-gases of NOx in oxidative conditions in the presence of hydrocarbon. Catalyst for cleaning off-gases of nitrogen oxides by catalytic reduction of methane in oxidative medium comprises 1.75-2.0 wt % of palladium applied on carrier. The latter represents Mg(Sr)-Al-O oxide composition containing 4-14 wt % of Mg(Sr)O with specific surface (3.8 - 9.0) m2/g and moisture content of (0.35-0.65) ml/g. Invention covers the method of making the catalyst including manufacturing Mg-Al-O and Sr-Al-O carriers and that of cleaning off-gases from nitrogen oxides by catalytic reduction by hydrocarbons in oxidative atmosphere in the presence of above described catalyst including palladium applied on Mg-Al-O or Sr-Al-O carrier.
EFFECT: efficient cleaning.
