Experimental Study on Feasibility of Catalytic Denitrification by Rare Earth Tailings AITranslate
Abstract AITranslate
X-ray fluorescence spectrometer(XRF),X-ray diffractometer(XRD) and scanning electron microscopy(SEM) were used to characterize the rare earth tailings.It is found that there are many elements in the tailings,and the relationship among minerals is complex.According to the characteristics of rare earth tailings,the catalytic denitrification performance of rare earth tailings was tested in a vertical tube furnace.The results show that NO conversion rate increases with the increase of reaction temperature and gas residence time,and NO conversion rate in fixed bed reactor is higher than that in bubbling bed reactor.When the reaction temperature is 800 ℃,NO conversion rate reaches 98.7%.The denitration catalyst was prepared by grinding and roasting with pseudo-boehmite and rare earth tailings as raw materials.When the total amount of rare earth tailings remains unchanged,the NO conversion rate increases with the increase of pseudo-boehmite mass.When the reaction temperature is 600 ℃,the NO conversion rate of the catalyst with the mass ratio of pseudo-boehmite to rare earth tailings of 1∶2 is 15% higher than that of the pure rare earth tailings.The thermodynamic calculation proves that the rare earth tailings with high iron content is feasible for CO reduction denitrification.
