Abstract

A series of single metal oxide catalysts were prepared and their catalytic activities were investigated for simultaneous removal of soot and NO_x in an oxygen rich condition. Effects of contact intensity between catalyst and soot as well as simultaneous removal paths for soot and NO_x were also studied. Results showed that metal oxide catalysts of Cr, Mn, Co, and Ni exhibited high activities for simultaneous removal of soot and NO_x and still had high activities in the loose contact mode between catalyst and soot. Simultaneous removal paths found were that NO₂ formation by oxidation of NO promoted soot oxidation and CO formation by soot oxidation reduced NO_x.
