The paper reports results of experiments to study elemental mercury (Hg) and mercuric chloride (HgCl[sub 2]) capture by several calcium-based sorbents and their performance compared with an activated carbon used in earlier bench- and pilot-scale tests. Elemental Hg and HgCl[sub 2] concentrations were roughly 2--3 ppb in a simulated flue gas. Among the calcium-based sorbents evaluated in the study are reagent grade hydrated lime, a mixture of fly ash and hydrated lime (Advacate), and a modified Advacate. Capture of elemental Hg and HgCl[sub 2] by these sorbents was studied at 100 C.
