Abstract

PURPOSE: To promote NH3-forming reaction and to increase NOx-removal ratio by the contact of exhaust gas containing a large amount of hydrogan and NOx with a Pt group catalyst and circulating one portion of the exhaust gas which has passed the catalyst layer to the exhaust gas to be treated.
