| Abstract: | The mechanism and kinetics of the supported vanadium oxide DeNOx(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. |
