Catalytic oxidation of Hg0 by MnOx–CeO2/γ-Al2O3 catalyst at low temperatures

Catalytic oxidation of elemental mercury by Mn–Mo/CNT at low temperature

“…Equation 1 defines the mercury oxidation efficiency of these catalysts, and the detail of in this equation was listed in references [18,24,29,30]. The other reason that equation 1 was defined as the mercury oxidation efficiency was that nearly all the change in the elemental mercury concentration was existed in the form of oxidized mercury (including oxidized mercury released to the flue gas and mercury oxidized on the catalyst surface), and the detail discussion was listed in part 3.2.…”

“…Subsequently, the manganese oxide with a low valence would be re-oxidized to a high valence in the presence of O 2 . Equation 1 to equation 4 are the main process [16,30].…”

A novel low temperature catalyst regenerated from deactivated SCR catalyst for Hg0 oxidation

“…As stated above, there have been many studies focusing on the MnO x -based supported catalysts for Hg 0 oxidation at low temperature [13,15,18,[27][28][29][30]. For comparison, the Hg 0 oxidation activity of the MSCR-II in the present work, the MnO x supported on the carbon nanotube (Mn/CNT) [15] in our previous study and that reported in the literature are summarized in Fig.…”

Regeneration mechanism of CeO2-TiO2 sorbents for elemental mercury capture from syngas

“…6. The CeTi sorbent after adsorption significantly released mercury from 250-280 o C. No obvious Hg 2+ was observed during the entire regeneration process, indicating that mercury compounds were decomposed at high temperatures [22,23]. Note that a desorption peak was also detected at temperatures lower than 200 o C, which could be due to the release of weakly bound mercury species [24,25].…”
