| 摘 要： | 为了获得性能高效的非碳基吸附剂脱除燃煤烟气中排放的Hg,采用液溴浸渍的方法,对吸附剂进行了改性。通过固定床和沉降炉吸附实验,发现高岭土、沸石和石灰石改性后对单质汞的吸附能力有较大提高。改性后的吸附能力提高的原因在于化学吸附的增强。

| Abstract: | Bromine impregnation was used to improve the mercury capture capability of three non-carbon sorbents,which had potential to be used for the removal of elemental mercury vapor from coal combustion flue gases.It was found that the mercury capture abilities of kaolin,zeolite and lime stone were enhanced by Br-impregnation due to the enhancement of chemiadsorption. |
