| 摘 要： | 研究了Ｏ２和Ｈ２Ｏ对沥青基球状活性炭（ＰＳＡＣ）吸附ＳＯ２能力的影响。结果表明，Ｏ２和ＳＯ２占据不同的活性中心，而Ｈ２Ｏ和ＳＯ２占据同一类活性中心，且ＳＯ２与活性中心的结合能力比Ｈ２Ｏ强得多。Ｏ２或Ｈ２Ｏ均能提高ＰＳＡＣ对ＳＯ２的吸附能力。ＳＯ２吸附量的增加来源于ＳＯ２的化学吸附量。

| Abstract: | The influence of O2 and H2O on the adsorption of SO2 over pitch-based spheric activated carbon (PSAC) has been investigated. The results indicated that O2 and SO2 occupied different kinds of active cites, wherese H2O and SO2 competed the same sort of active cites on the surface of PSAC, and the force of SO2 bonded to carbon was much stronger than that of H2O. The amount of SO2 adsorbed over PSAC could be enhanced by O2 or H2O. The increase of the amount of SO2 adsorbed came from the amount of chemically bonded SO2. |
