| 英文摘要 | Gas-phase elemental mercury (hg-0) capture by an activated coke (ac) supported v2o5 (v2o5/ac) catalyst was studied in simulated flue gas and compared with that by the ac. the study on the influences of v2o5 loading, temperature, capture time and flue gas components (o-2, so2, h2o and n-2) shows that the hg-0 capture capability of v2o5/ac is much higher than that of ac. it increases with an increase in v2o5 loading and is promoted by o-2. which indicates the important role of v2o5 in hg-0 oxidation and capture; it is promoted slightly by so2 but inhibited by h2o; it increases with an increase in temperature up to 150 degrees c when hg desorption starts. x-ray photoelectron spectroscopy analysis and sequential chemical extraction experiments indicate that the main states of hg captured on v2o5/ac are hgo and hgso4. temperature programmed desorption experiments were also made to understand the stability of the hg captured.
