Abstract

The removal characteristics of an activated carbon (AC) and an iron oxide for the removal of Hg vapor were studied. The AC removed a negligible amount of mercury at 150°C in the presence of SO₂ or H₂S. However, in the presence of both SO₂ and H₂S, the AC could remove considerable amount of mercury. The activity of the iron oxide for the Hg removal increased with the decrease of the reaction temperature. Sulfur formed from H₂S over the iron oxide contributed to the Hg removal and the surface oxygen or part or the lattice oxygen of the sample iron oxide contributed in the formation of sulfur from H₂S. The presence of H₂O slowed down the Hg removal at 60°-150°C.
