Abstract

PURPOSE: To remove NOx in the exhaust gas economically and, moreover, in a high degree, by reducing NOx in the exhaust gas by adding a petroleum fuel to the exhaust gas containing NOx, then, by reducing the remaining NOx to N2 by adding a gas containing NH3 and, at the same time, by oxidizing the unburned part.
