The reduction of SO2, HCl, and NO(x) concentrations using calcium magnesium acetate (CMA) as a novel sorbent in a simulated municipal waste incinerator flue gas was investigated. The reduction of individual SO2, HCl, and NO(x) concentrations was tested at 850 degrees C and it was found that CMA could reduce the SO2 concentration by 74%, HCl concentration by 64%, or NO(x) concentration by 94%. It was observed that individual SO2 or HCl capture increased with increasing initial oxygen concentration in the reacting gas or increasing sorbent input. NO(x) reduction decreased with increasing initial oxygen concentration in the reacting gas. The simultaneous reduction of SO2, HCl, and NO(x) concentrations by CMA was also investigated. It was found that CMA could simultaneously capture 60% SO2 and 61% HCl and reduce NO(x) concentrations by 26%, when the initial oxygen concentration in the reacting gas was 4%. During the simultaneous reduction of SO2, HCl, and NO(x), it was noted that as the initial oxygen concentration in the reacting gas increased, the efficiency of SO2 capture increased too, but the efficiency of HCl capture and the efficiency of NO(x) destruction decreased.
研究了在模拟城市垃圾焚烧炉烟气中使用乙酸钙镁（CMA）作为新型吸附剂来降低二氧化硫、氯化氢和氮氧化物（NO(x)）浓度的情况。在850摄氏度下测试了二氧化硫、氯化氢和氮氧化物（NO(x)）各自浓度的降低情况，发现CMA可使二氧化硫浓度降低74%，氯化氢浓度降低64%，或氮氧化物（NO(x)）浓度降低94%。观察到，二氧化硫或氯化氢的单独捕获量随着反应气体中初始氧气浓度的增加或吸附剂投入量的增加而增加。氮氧化物（NO(x)）的还原率随着反应气体中初始氧气浓度的增加而降低。还研究了CMA同时降低二氧化硫、氯化氢和氮氧化物（NO(x)）浓度的情况。结果发现，当反应气体中的初始氧气浓度为4%时，CMA可同时捕获60%的二氧化硫和61%的氯化氢，并使氮氧化物（NO(x)）浓度降低26%。在同时降低二氧化硫、氯化氢和氮氧化物（NO(x)）的过程中，注意到随着反应气体中初始氧气浓度的增加，二氧化硫的捕获效率也增加，但氯化氢的捕获效率和氮氧化物（NO(x)）的破坏效率降低。
