Catalytic properties of ZnO-modified copper ferrite catalysts in water-gas shift reaction
摘要
Abstract
The catalytic properties of ZnO-modified copper ferrite in water-gas shift ( WGS) reaction were evaluated between 250 and 400℃.The Zn2.5-Cu/Fe (modified by 2.5%ZnO) showed high catalytic activity.The catalyst was characterized with XRD, SEM, H2-TPR and CO2-TPD techniques and N2 sorption experiment.It was shown that intro ducit on of pa proprita e amounts of ZnO transformed the CuFe2 O4 from the tetrahedral crystalline phase to the cubic, enhanced the CuFe2 O4 reducibility, and increased the amount of weak and medium basic sites.As a consequence, the interaction between copper and iron species was improved andt he catalytic activity was increased.关键词
