<p>A process for treating exhaust gas from internal combustion engines wherein the combustion exhaust gas contains HC, CO, O2, soot and possibly NOx. In treating the combustion exhaust gas, HC is oxidized to COx and H2O: NO, if present, is oxidized to NO2 and soot is oxidized by reaction with NOx. In addition, NOx is generated by oxidizing ammonia and NOx is introduced into the exhaust gas upstream of the oxidization of soot by reaction with NOx.</p> |
