The catalyst, with an optimal loading of 5.8% cobalt species, attained approximately 95% Hg0 removal efficiency at 150 \u00b0C under simulated flue gas atmosphere. O2 could enhance the Hg0 removal activity of magnetospheres catalyst via the Mars-Maessen mechanism. SO2 displayed an inhibitive effect on Hg0 removal capacity. NO with lower concentration could promote the Hg0 removal efficiency. However, when increasing the NO concentration to 300 ppm, a slightly inhibitive effect of NO was observed. In the presence of 10 ppm of HCl, greater than 95.5% Hg0 removal efficiency was attained, which was attributed to the formation of active chlorine species on the surface. H2O presented a seriously inhibitive effect on Hg0 removal efficiency. Repeated oxidation\u2013regeneration cycles demonstrated that the spent Co\u2013MF catalyst could be regenerated effectively via thermally treated at 400 \u00b0C for 2 h.<\/jats:p>","DOI":"10.1021\/es504419v","type":"journal-article","created":{"date-parts":[[2014,11,17]],"date-time":"2014-11-17T12:21:59Z","timestamp":1416226919000},"page":"14837-14843","source":"Crossref","is-referenced-by-count":153,"title":["Regenerable\nCobalt Oxide Loaded Magnetosphere Catalyst\nfrom Fly Ash for Mercury Removal in Coal Combustion Flue Gas"],"prefix":"10.1021","volume":"48","author":[{"given":"Jianping","family":"Yang","sequence":"first","affiliation":[{"name":"Huazhong University of Science and Technology , , ,","place":["Wuhan, People\u2019s Republic of China, 430074"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yongchun","family":"Zhao","sequence":"additional","affiliation":[{"name":"Huazhong University of Science and Technology , , ,","place":["Wuhan, People\u2019s Republic of China, 430074"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Junying","family":"Zhang","sequence":"additional","affiliation":[{"name":"Huazhong University of Science and Technology , , ,","place":["Wuhan, People\u2019s Republic of China, 430074"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chuguang","family":"Zheng","sequence":"additional","affiliation":[{"name":"Huazhong University of Science and Technology , , ,","place":["Wuhan, People\u2019s Republic of China, 430074"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"316","published-online":{"date-parts":[[2014,11,17]]},"reference":[{"key":"2026081502061290300_cit1","author":"UNEP","year":"2013"},{"key":"2026081502061290300_cit2","doi-asserted-by":"crossref","first-page":"89","DOI":"10.1016\/S0378-3820(03)00059-6","article-title":"Status\nreview of mercury control\noptions for coal-fired power plants","volume":"82","author":"Pavlish","year":"2003","journal-title":"Fuel Process.\nTechnol."},{"key":"2026081502061290300_cit3","doi-asserted-by":"crossref","first-page":"426","DOI":"10.1021\/es9021206","article-title":"Catalytic oxidation\nof elemental mercury over the modified catalyst Mn\/\u03b1-Al2O3 at lower temperatures","volume":"44","author":"Li","year":"2010","journal-title":"Environ.
