Process for catalytic reduction of nitrogen oxides by making use of hydrocarbon mixtures and hydrogen peroxide

摘要

the dosage of hydrogen peroxide or peroxide vodu00edkua hydrocarbon to exhalu00e1tu containing nitrogen oxides, which are conducted through the catalyst based on stru00edbra for temperature 150 when 550.degree.c, are efektivneodstraneny nitrogen oxides, their reduction to nitrogen. the method is urcena for obstacle exhalu00e1tu with oxidacnu00ed nitrogen oxide in atmosphere.especially the high degree reduction nitrogen oxide to nitrogen is reached pouzitu00edm catalyst layers on stru00edbra alumine or stru00edbra in zeolite ttfn - 5 at temperatures of 200 to 400.degree.c.method is suitable for the nitrogen oxide contained in exhalu00e1tech obstacle with oxidacnu00ed atmosphere originating from mobile and stationary sources.
