Effect of H_2-regeneration on SO_2 removal activity of V_2O_5-CoO/AC
|
Abstract:
Elemental sulfur can be produced simultaneously during H2-regeneration of SO2-adsorbed V2O5-CoO/AC catalyst-sorbent when effluent gas of the regeneration is recycled back to the reactor. SO2 removal activities of the catalyst-sorbents after the regeneration under different conditions were studied in detail. It is found that elemental sulfur production requires transformation of sulfur forms between the solid phase and the gas phase, which results in residual sulfur in the catalyst-sorbent and a decrease in ...
