Investigation on Effect of CexLa1-x Active Component on Denitration Performance of NH3-SCR AITranslate
Abstract AITranslate
In order to explore the effect of the combined action of Ce and La in natural bastnaesite on denitration performance,the CexLa1-x active component was prepared by microwave heating and loaded onγ-Al2O3 for activity test.Ce0.8La0.2 catalyst has the best denitration effect and 78%NO conversion at 350℃.The results of BET,NH3-TPD,XRD,Raman and XPS show that the active component of Ce0.8La0.2 catalyst is a solid solution containing Ce and La,which has better adsorption capacity of NH3 and higher specific surface area,and the surface adsorption of oxygen on Ce0.8La0.2 catalyst is one of the reasons for improving the catalytic performance of NH3-SCR.
