英文摘要 | The Co/Fe/Al2O3/cordierite catalysts with different Co loadings were prepared by sol-gel and impregnation methods, and their performance in the selective catalytic reduction of NO with C3H6 over catalytic were experimentally studied in a ceramic tubular reactor. The results indicated that 1.5Co/Fe/Al2O3/cordierite showed the highest C3H6-SCR activity with 97% NO reduction in the simulated flue gas at 550 . Cobalt was able to effectively improve the ability of Fe/Al2O3/cordierite catalysts to resist SO2 and H2O in flue gas. When 0.02% SO2 and 3% water vapor were added to the simulated flue gas, the NO reduction efficiency of 1.5Co/Fe/Al2O3/cordierite was almost unaffected, the NO reduction by 1.5Co/Fe/Al2O3/cordierite with C3H6 all surpassed 90%. In contrast, the catalytic activity of Fe/Al2O3/cordierite without cobalt modification was seriously suppressed by SO2 and H2O, the highest NO reduction efficiency of Fe/Al2O3/cordierite was less than 50% within the entire reaction temperature range (200-700 ).XRD and SEM results showed that the surface of 1.5Co/Fe/Al2O3/cordierite after the modification by cobalt became loose, and formed by the cobalt iron and cobalt aluminum metal oxide-based spherical grains.H2-TPR results showed that 1.5Co/Fe/Al2O3/cordierite had better low temperature reduction performance than Fe/Al2O3/cordierite. Py-FTIR results confirmed that Co can dramatically increased the Lewis acid and produced Br∅nsted acid on the catalyst surface. N2 adsorption/desorption characterization results proved that Co can increase the specific surface area of the catalyst. © 2018, Science Press. All right reserved. |
