Abstract

Abstract

The catalytic effect of several metallic oxides(Fe₂O₃, Cr₃O₃ and Ni₂O₃) on elimination of NO has been studied in a flow type reactor, and the roles of metallic oxide in the elimination reactions of NO has also been discussed. The results show that in the system of NO-CO-CO₂-N₂, the catalytic reaction of NO/CO on the metallic oxide plays a leading role in NO elimination especially for Fe₂O₃ and Cr₂O₃ samples. However, Ni₂O₃ and its pre-reduced samples show extremely remarkable catalytic effect on direct decomposition of NO.
