| Synopsis: |
"In order to gain a more complete understanding of the impact of SOx on ACI, mercury capture was tested under varying conditions of SO2 and SO3
concentrations using a packed bed reactor and simulated flue gas (SFG). The final mercury content of the activated carbons is independent of the SO2 concentration in the SFG, but the presence of SO3 inhibits mercury capture even at the lowest concentration tested (20 ppm). The mercury
removal capacity decreases as the sulfur content of the used activated carbons increases from 1 to 10%. The results suggest that mercury and sulfur oxides are in competition for the same binding sites on the carbon surface."
