Effects of Chlorine Addition on Nitrogen Oxide Reduction and Mercury Oxidation over Selective Catalytic Reduction Catalysts.

ABSTRACT: The effect of chlorine on mercury oxidation and nitrogen oxides (NO _x ) reduction over selective catalytic reduction (SCR) catalysts was investigated in this study. Commercial SCR catalysts achieved a high Hg⁰ oxidation efficiency when Cl₂ was sprayed into the flue gas. Results indicated that an appropriate concentration of Cl₂ was found to promote NO _x reduction and Hg⁰ oxidation significantly. An optimal concentration of Cl₂ (25 ppm) was found to significantly promote NO _x reduction and Hg⁰ oxidation. Moreover, we studied the effects of Cl₂ on NO _x reduction and Hg⁰ oxidation over SCR catalysts under different concentrations of SO
