| Abstract | The scope of the work was to study adsorption of Hg(elemental) by thermally activated carbons and HgCl2 by Ca(OH)2. While the focus of the previous investigations was mainly on a screening type of comparison between these sorbents, this work investigates the fundamental and quantitative dependence of the adsorption capacity of sorbents and mercury removal on sorption parameters such as temperature, gas-phase mercury species concentration, and flue gas species (SO2). The experiments were performed in a laboratory-scale, fixed-bed apparatus, in which the inlet gas containing nitrogen, Hg(elemental) or HgCl2, and, on occasions, SO2 were contacted with sorbents. |
