METHOD FOR SIMULTANEOUSLY ABATING NITRIC OXIDES AND NITROUS OXIDES IN GASES CONTAINING THEM

摘要

: Process for simultaneously scrubbing, by reduction with ammonia, the nitric oxides (NO^) and nitrous oxide (N2O) in gases containing from 100 to 7 000 ppmv thereof, at the same time as oxygen and water, which consists - in bringing the ammonia content of these gases to values 0. "7 X 1.4 [X = ammonia/nitrogen oxides, volumic ratios), - in circulating these gases at temperatures of between 200 and 600°C, on a catalyst comprising an iron beta zeolite.
