| Abstract | The paper gives results of an examination of the effects of hydrogen chloride (HC1, 50 ppm) and sulfur dioxide (SO2, 1000 ppm) on the capture of (1) elemental mercury (Hg-o, 40 ppb) by a thermally activated carbon (FGD), and (2) mercuric chloride (HgCl12, 73 ppb) by calcium hydroxide--Ca(OH)2. Comparisons between a carbon-based sorbent (FGD), Ca(OH)2, and coal combustion residues (fly ash, bottom ash, and scrubber sludge) revealed that non-carbon-based sorbents with relatively high calcium (Ca) content can effectively remove HgCl12 from a simulated flue gas. HgCl12 removals of up to half of the removal shown by FGD were observed with some of the non-carbon-based sorbents. |
