A New SOx Deactivation-Free NOx Reduction System Using Rh/Alumina and Periodical Rich and Lean Conditions
A SOx deactivation free catalytic NOx reduction system in the presence of excess oxygen has been demonstrated. This system functioned well in the periodical two steps, which consisted of a short operation in oxidizing conditions and a far shorter operation in reducing conditions. In this system, only a Rh catalyst effectively catalyzed NOx reduction. In the presence of 50 ppm SOx, this system did not deteriorate at all.
