Title
Synergetic catalytic removal of Hg0 and NO over CeO2(ZrO2)/TiO2
Abstract

•The CeO2(ZrO2)/TiO2 catalyst exhibited high efficiency for Hg0 catalytic oxidation.•The catalytic performance for NH3-SCR of NO was not affected.•O2 obviously improved catalytic oxidation of Hg0 for its oxidation susceptibility.

A series of CeO2(ZrO2)/TiO2 monolith catalysts were investigated for catalytic oxidation of Hg0 and NH3-SCR of NO. Effect of flue gases components on catalytic oxidation of Hg0 was mainly studied. Results showed that the CeO2(ZrO2)/TiO2 catalyst exhibited high efficiency for catalytic oxidation of Hg0 at 240–400 °C without adding other oxidant, and its catalytic performance for NH3-SCR of NO was not affected. NH3 had slight inhibitory effect while SO2 and NO had no influence on catalytic oxidation of Hg0, but O2 obviously improved catalytic oxidation of Hg0 for its oxidation susceptibility.
