摘要

In this work, a catalytic membrane using Mn/Mo/Ru/Al O as the catalyst was employed to remove elemental mercury (Hg ) from flue gas at low temperature. Compared with traditional catalytic oxidation (TCO) mode, Mn/Al O membrane catalytic system had much higher removal efficiency of Hg . After the incorporation of Mo and Ru, the production of Cl from the Deacon reaction and the retainability for oxidants over Mn/Al O membrane were greatly enhanced. As a result, the oxidization of Hg over Mn/Al O membrane was obviously promoted due to incorporation of Mo and Ru. In the presence of 8 ppmv HCl, the removal efficiency of Hg by Mn/Mo/Ru/Al O membrane reached 95% at 423 K. The influence of NO and SO on Hg removal were insignificant even if 200 ppmv NO and 1000 ppmv SO were used. Moreover, compared with the TCO mode, the Mn/Mo/Ru/Al O membrane catalytic system could remarkably reduce the demanded amount of oxidants for Hg removal. Therefore, the Mn/Mo/Ru/Al O membrane catalytic system may be a promising technology for the control of Hg emission.
