| 英文摘要 | H(2) regeneration of an activated carbon supported vanadium and cobalt oxides (v(2)o(5)-coo/ac) catalyst-sorbent used for flue gas so(2) removal is studied in this paper. elemental sulfur is produced during the h(2)-regeneration when effluent gas of the regeneration is recycled back to the reactor. the regeneration conditions affect the regeneration efficiency and the elemental sulfur yield. the regeneration efficiency is the highest at 330 degrees c, with so(2) as the product. the production of elemental sulfur occurs at 350 degrees c and higher with the highest elemental sulfur yield of 9.8 mg-s/g-cat. at 380 degrees c. a lower effluent gas recycle rate is beneficial to elemental sulfur production. intermittent h(2) feeding strategy can be used to control h(2)s concentration in the gas phase and increase the elemental sulfur yield. two types of reactions occur in the regeneration, reduction of sulfuric acid to so(2) by ac and reduction of so(2) to elemental sulfur through claus reaction. h(2)s is an intermediate, which is important for elemental sulfur formation and for conversion of coo to cos that catalyzes the claus reaction. the catalyst-sorbent exhibits good stability in so(2) removal capacity and in elemental sulfur yield.
