Abstract:
The activities of activated carbon fibers(ACFs) from ethylene tar pitch (ETP) and cellulose were examined for the oxidative conversion of SO2 into aq. H2SO4 in the presence of O2 and H2O. The results indicated that Cellulose ACF showed much higher activity than ETP ACF, owning to higher ability of SO2 adsorption, higher catalytic activity for the oxidation of SO2 to SO3 and larger amount of H2O adsorption, enhanced catalytic activity for the oxidation of SO2 to SO3 showed highest among these abilities. These in turn depend on nitrogencontaining group and some oxygen-containing group in the surface of cellulose ACF, so the SO2 removal activity of ACFs is affected by functional groups.

摘要:
研究了在O2和H2O存在下,乙烯渣油沥青基活性炭纤维(ETPACF)和粘胶基活性炭纤维(CelluloseACF)的脱硫活性.结果表明,在比表面积相近的情况下,ETPACF的脱硫活性明显低于CelluloseACF,这可归因于后者具有较强的吸附和催化氧化SO2能力及较大的吸水量,尤其是具有较强的催化氧化SO2的能力,这些能力又与其表面含有含氮官能团以及某些含氧官能团有关,因此ACF的表面官能团对其脱硫活性影响很大.
