Remove elemental mercury from simulated flue gas by CeO2-modified MnOx/HZSM-5 adsorbent
In this study, we synthesized a Ce-modified Mn/HZSM-5 adsorbent via the ultrasound-assisted impregnation for Hg 0 capture. Given the addition of 15% CeO 2 , ~ 100% Hg 0 efficiency was reached at 200 °C, suggesting its promotional effect on Hg 0 removal. The doped Ce introduced additional chemisorbed...

capture. Given the addition of 15% CeO
2
, ~ 100% Hg
0
efficiency was reached at 200 °C, suggesting its promotional effect on Hg
0
removal. The doped Ce introduced additional chemisorbed oxygen species onto the adsorbent surfaces, which facilitated the oxidation of Hg
0
to HgO. Even though adding CeO
2
led to a weakened adsorbent acidity, yet it appeared that this negative affect could be completely overcome by the enhanced oxidative ability, which finally endowed Ce-modified Mn/HZSM-5 with a satisfactory Hg
0
removal performance within the whole investigated temperature range. During the Hg
0
capture process, chemisorption was predominant with Mn
4+
operating as the main active site for oxidizing Hg
0
to Hg
2+
. Finally, the 15Ce-Mn/HZSM-5 adsorbent exhibited good recyclability and stability. However, its tolerance to H
2
O and SO
2
appeared relatively weak, suggesting that some modification should be conducted to improve its practicality. |
