主　　题：Al2O3 support TiO2 support NO removal Hg-0 oxidation 

摘      要：TiO2 and Al2O3 were applied as supports to prepare various Cu-based and Fe-based SCR catalysts, and the synergetic removal of NO and Hg-0 over these catalysts was tested in a fixed-bed experimental system, in order to explore the effect of TiO2 and Al2O3 on the simultaneous removal of NO and Hg-0 over Cu and Fe catalysts. Experimental results indicated that Al2O3 showed better performance as the catalyst support than TiO2. Characterization results demonstrated that Al2O3 helped significantly increase the surface area and the pore volume of catalysts, so it promoted the adsorption ability to adsorb more reactant gas, which favored the removal of NO and Hg-0. Moreover, Al2O3 resulted in the increase of the absorbed oxygen amount, indicating the increase of the active oxidative sites and the stronger oxidation ability for Hg-0. The work could contribute to providing a potential high-performance support choice adopted to develop efficient catalysts for simultaneous removal of NO and Hg-0. (C) 2018 Energy Institute.
