Abstract: The modification of industrial activated carbon 4# (AC4) with sulfonated cobalt phthalocyanine (CoPcS) impregnant and the adsorption capacities of NaOH，Cu(AC)2，CoPcS toward H2S were studied in comparison，leading to the result：CoPcS＞Cu(AC)2＞NaOH. The effects of reaction conditions were investigated. The fresh activated carbon and modified activated carbon before and after H2S adsorption were characterized by SEM. The results showed that the optimum conditions were at 60℃ with 1.5% of oxygen content. Furthermore，SEM distribution indicated that the result of adsorption became obviously better by the change of pore structure of modified activated carbon and the formation of surface active materials.

摘要： 以工业4#活性炭为载体，制备磺化酞菁钴(CoPcS)改性活性炭，对比研究了NaOH、Cu(AC)2、CoPcS改性活性炭在相同条件下净化H2S的吸附性能为：CoPcS＞Cu(AC)2＞NaOH；考察了反应条件对净化电石炉尾气中的H2S气体的影响；并对空白活性炭、改性活性炭吸附前后作SEM表征分析。结果表明，反应温度60℃、氧含量1.5%为改性活性炭的最佳反应条件。结合SEM表征分析表明：改性活性炭孔结构的变化和表面活性物质的生成使其对H2S的吸附净化效果增强。
