Influence of La₂O₃ on NO_x Emission in Iron Ore Sintering

Abstract:

NO_x emission in coke combustion with and without La₂O₃ was investigated in a fixed bed quartz reactor. The effects of La₂O₃ loading and lanthanum oxide particle size on NO_x emission were discussed. NO_x emission was also studied by sintering pot tests with lanthanum oxide modified coke as sintering fuel. The results showed that lanthanum oxide was catalytically active in promoting not only coke combustion but also NO_x reduction. In coke combustion experiments, NO_x and CO emission decreased with increasing lanthanum oxide loading up to 2.0wt% and decreasing lanthanum oxide particle size (28~150μm).
