| Résumé : | Cupric chloride-impregnated activated carbon sorbents (CuCl2-ACs) showed good performance in Hg0 oxidation and adsorption in previously published entrained-flow test results. In addition, our previous studies indicated that Hg0 is oxidized by CuCl2-ACs and the resultant oxidized mercury is readsorbed onto the sorbents. This study conducted mathematical modeling to interpret these previous results and better understand the Hg0 oxidation and adsorption mechanism of CuCl2-ACs. As a result, the mathematical modeling results confirmed that Hg0 oxidation by CuCl2-ACs is determined by the injection level of CuCl2 impregnated onto the sorbents. An increase in CuCl2 loading in CuCl2-ACs was found to increase Hg0 oxidation but very slightly increased Hg adsorption because an increase in CuCl2 loading decreased the active CuCl2-free carbon sites available for the readsorption of resultant oxidized mercury on the surfaces and inside the pores. |
