Mn-Based perovskite oxides combined with a temperature swing adsorption (TSA) process were employed for Hg0 adsorption and regeneration from coal-fired flue gas, in which oxygen directly acted as oxidant to enhance the capture of Hg0. Three kinds of Mn-based perovskie oxides, SrMnO3, LaMnO3 and CeMnO3 were evaluated. The results indicated that the performances for Hg0 removal decreased in the order...
To simultaneously remove elemental mercury (Hg0) and NOx at low temperature from flue gas in coal-fired power plants, an efficient NH3-SCR LaMnO3 perovskite oxide was chosen as the catalyst for Hg0 removal. The physicochemical properties, surface reaction and mercury desorption were investigated using BET, XRD, XPS, H2-TPR and Hg-TPD, to investigate the Hg0 capture mechanism over LaMnO3 oxides. The...
