Abstract
Illinois coal-derived activated carbons (ICDACs) were prepared in a fluidized bed reactor. Mercury adsorption tests were then compared with a simulated flue gas. The gas stream contained 40-60 μ g/Nm3 Hg /HgCl2 at 135°C and 1 atm. Hg0 adsorption capacity and reactivity of some ICDACs were higher than those for FGD. However, FGD demonstrated better HgCl2 adsorption capacity. ICDACs were also treated with sulfur at 200 and 600°C to evaluate the effectiveness of sulfur impregnation for mercury capture. Sulfur impregnation significantly improved HgCl2 capture. Overall, the results indicate that the adsorption mechanisms of Hg0 and HgCl2 on ICDACs may be different.
