摘要
研究了O_2和H_2O对沥青基球状活性炭（PSAC）吸附SO_2能力的影响,结果表明,O_2和SO_2占据不同的活性中心,而H_2O和SO_2占据同一类活性中心,且SO_2与活性中心的结合能力比H_2O强得多,O_2或H_2O均能提高PSAC对SO_2的吸附能力,SO_2吸附量的增加来源于SO_2的化学吸附量。
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.
