| 英文摘要 | The activated carbon (ac)-supported v2o5 catalyst-sorbent, v2o5/ac, was found to be very effective for the simultaneous removal of so2 and no from flue gas at 200 degrees c. the catalyst-sorbent, however, may suffer from high carbon loss during periodical regeneration required by the so2 removal process. the so2-adsorbed v2o5/ac catalyst-sorbent could be regenerated in the presence of nh3 at low temperature (300 degrees c), and the carbon burn-off is much less than that in an inert atmosphere. in this study, the behaviors and mechanism of carbon burn-off during the regeneration of v2o5/ac in 5% nh3-95% ar were studied using temperature-programmed desorption, elemental analysis, x-ray photoelectron spectroscopy, and fourier transform infrared spectroscopy. the carbon consumption amount for the regeneration carried out in 5% nh3-95% ar is much lower than that in ar atmosphere. the presence of nh3 inhibits the carbon burn-off by reacting with the surface oxygen-containing groups in v2o5/ac, -cooh, -oh, and v2o5 etc, to produce h2o and nitrogen-containing groups such as -conh2, c-n, and c n. |
