Abstract

Abstract

In this paper, the mixture of fly ash and carbide slag(FC) was used as the carrier, Na₂O as the active component, and the adsorbent x% Na₂O/FC(x% represents the mass ratio of active component Na₂O in the adsorbent) was prepared by ultrasonic impregnation method. The adsorbents were characterized by XRD, BET and SEM, and the mechanism of simultaneous desulfurization and denitration of adsorbents under microwave radiation was discussed. The results showed that Na₂O loading under microwave significantly improved the performance of the adsorbent. Simultaneous desulfurization and denitrification performance of 6%Na₂O/FC was the best. The desulfurization t_90% and t_50%(t_x_% was the reaction time when the desulfurization rate of adsorbents or the denitrification rate reached x%) were 12 min and 73 min, and the denitrification t_90% and t_50% were 4 min and 16 min. The mechanism analysis showed that the simultaneous desulfurization and denitration process was dominated by physical adsorption at first, and chemical adsorption after a period of reaction. The chemisorption process of Na₂O/FC adsorbent under microwave was found as follows: SO₂ and NO were oxidized into SO₃ and N₂O₅ by active oxygen species, and SO₃ and N₂O₅ reacted with metal oxides to generate sulfates and nitrates such as Ca₅(SiO₄)₂SO₄,(Mg_xCa_1-_x)(NO₃)₂ and CaSO₄. At the same time, the active component Na₂O directly reacted with the adsorbed SO₂ and NO to form Na₂SO₃ and NaNO₃.
