Experimental Study on Catalytic Reduction of NO with CO by Bayan Obo Rare Earth Tailings AITranslate
Abstract AITranslate
Experimental study was conducted on the reduction of NO,using CO as the reductant and rare earth tailings as the catalyst.The experimental results show that rare earth tailings can effectively catalyze the reduction of NO,and the denitration rate increases as the reaction temperature and the carbon-to-nitrogen ratio increase.The denitration rate of rare earth tailings in the middle and high temperature section is higher than that of the pure substances of CeO2,Fe2O3,Fe2O3/CeO2 and 5 Fe2O3/CeO2.H2-TPR test shows that the reduction peaks of rare earth tailings above 800℃are also higher than those of the four pure substances.XRD analysis shows that the main mineral phases of the rare earth tailings have no change before and after denitration reaction.However,the intensity of characteristic peaks of each mineral phase decreases,and the characteristic peak of bastnaesite disappears.SEM images show that cracks and pores appear in rare earth tailings after denitration reaction.EDS analysis shows that there are overlapping areas of multiple metal elements in a single particle of tailings.XPS analysis shows that the proportions of Fe3+and Ce3+in the tailings increase after denitration reaction.When the reaction temperature is 800℃and the carbon-to-nitrogen ratio is 4∶1,the denitration rate is 98%by rare earth tailings.
