Abstract

Iron oxide (Fe₂O₃) desulfurization sorbent was prepared from FeSO₄ and NH₄HCO₃ by precipitation method, and its regeneration behavior under different atmosphere was studied by using Thermos gravimetric analyzer. It is found that the regeneration of Fe₂O₃ desulfurization sorbent is the best in the synergy of SO₂-O₂atmosphere. When the concentration of O₂ or SO₂ in the synergy of SO₂-O₂atmosphere was increased, the regeneration time can be reduced, which is beneficial to the regeneration of iron oxide desulfurization sorbent. The regeneration of Fe₂O₃ desulfurization sorbent in the synergy of SO₂-O₂atmosphere can not only prevent sorbent sintering in single O₂ atmosphere but also improve the rate of regeneration in single SO₂ atmosphere.
