摘要 对于钒氧化物负载型催化剂在NH3-SCR过程中的反应机理和动力学已有较多研究。研究表明反应气体在催化剂表面的吸附-脱附过程对于SCR催化反应具有重要意义。本文概述了钒氧化物催化剂载体和表面物种在催化反应中的作用机理,以及H2O、SO2对NH3-SCR反应的影响,重点阐述了各种气相反应物的吸附形式以及反应作用机理。 The mechanism and kinetics of the supported vanadium oxide DeNO, （ SVO-DeNOx） catalyst in the NH3-SCR process have been extensively studied. It was found that the adsorption-desorption process of reactant gas on the surface of catalyst is of great importance to the SCR reaction. This article reviews the studies on the role of the SVO-DeNOx catalyst＇s support and the surface species in the catalytic reaction, and the influence of H2O and SO2 on NH3-SCR reaction. The adsorption form and reaction mechanism of gas-phase reactant are especially discussed.
