| 摘 要： | 利用制备的壳聚糖吸附剂在一维煤粉炉进行烟气除汞实验，实验发现：壳聚糖类吸附剂可以有效脱除燃煤烟气中的汞，最高效率可达到96％；并利用红外光谱分析了其微观结构，揭示了壳聚糖类吸附剂吸附螯舍痕量重金属汞汞机理为4个游离氨基螯合1个汞或2个游离氨基和2个羟基协同螯合一个汞。其中氨基是主要反应活性基。 |

| Abstract: | Aone-dimensionalfurnacetest bench experiment was conducted to study the Chitosan sorbent's adsorption efficiency of mercury in coal-fired flue gas.Three kinds of modified Chitosan(CTS)sorbents are prepared to remove the mercury in the flue gas.The CTS sorbents exhibit high mercury removal efficiency,as much as 96%.Fresh and after adsorption of the same kind of sorbents were compared by using Fourier transform infrared spectroscopy(FTIR).The results show that the mechanism of CTS removing mercury is that 4 f... |
