外文摘要：A series of rare earth elements (REE) modified Co/USY catalysts were prepared. Effects of REE-doped USY on the performance of Co/USY and on total combustion of benzene were evaluated. Characterization revealed that CeO2 enhanced the dispersion of Co3O4, which might promote the redox performance of Co/USY and enhance the catalytic performance. Catalytic tests showed that the highest catalytic activity of 10%Co-7.5%Ce/USY, and 100% benzene conversion was achieved at temperature below 250 degrees C. The high activity is likely attributed to Co3O4 particles with small size and high dispersion on USY and optimum synergistic interaction between highly dispersed CeO2 and Co3O4 particles.
