- W4220922210 abstract "• The bentonites modified with Ce-Fe binary oxides were prepared for Hg 0 removal. • A synergistic effect occurred between Fe-oxide and Ce-oxide during modification. • Fe incorporation could obviously improve the oxidization activity of Ce X Fe 4-X /Ben. • CeO 2 and Fe 2 O 3 served as active sites for Hg 0 removal from coal-fired flue gas. Mercury removal from coal combustion flue gas remains a great challenge for environmental protection because of the lack of cost-effective sorbents. This study prepared a series of bentonites modified with Ce-Fe binary oxides (Ce X Fe 4-X /Ben) for elemental mercury (Hg 0 ) capture from flue gas. The textural properties, crystal structure, magnetic properties, redox properties, and surface chemistry of Ce X Fe 4-X /Ben were characterized. The results testified that modification procedure had little effect on the pore shape and pore size of bentonite. During modification process, a synergistic effect occurred between iron oxide and cerium oxide and Ce-Fe binary oxides entered the interlayer of bentonite. The Ce X Fe 4-X /Ben samples presented far better Hg 0 removal performance compared with raw, Fe-modified, and Ce-modified bentonite. The optimum Ce/Fe molar ratio and adsorption temperature were 2:2 and 150–200 °C, respectively. O 2 , NO, and HCl promoted Hg 0 removal whereas SO 2 and H 2 O inhabited Hg 0 removal. The Hg 0 removal process was dominated by heterogeneous adsorption and Ce X Fe 4-X /Ben was used as a sorbent. Furthermore, the Hg 0 removal mechanism was revealed, where CeO 2 and Fe 2 O 3 served as active sites for Hg 0 removal. Multiple adsorption-regeneration cycles demonstrated that the deactivated Ce X Fe 4-X /Ben could be effectively regenerated after thermal treatment at 400 °C for 1 h under air atmosphere." @default.
