Process for removing nitrogen oxides in exhaust gases to nitrogen
TL;DR: In this paper, a process for reducing nitrogen oxides to nitrogen from exhaust gases is described, which involves bringing an exhaust gas containing nitrogen oxide into contact with at least one catalyst from proton-type zeolites, including metal oxides, by reaction with a hydrocarbon or an oxygen-containing organic compound in an oxidizing atmosphere containing excess oxygen.
