【摘要】 研究了商用活性炭纤维(Activated carbonf fiber-ACF)对二硫化碳(Carbon disulfide-CS2)的吸附性能,并与活性炭(Activated carbon-AC)、沸石吸附CS2的性能做了对比。重点考察了CS2浓度、吸附气流量、湿度和ACF含水量对CS2在ACF上吸附性能的影响。结果表明:相对于AC、沸石,ACF对CS2的吸附快、吸附率高,达46.5%;CS2浓度、吸附气流量增加,穿透点前移;湿度和含水量上升会明显降低ACF对CS2的吸附性能,当湿度升至65%时,吸附时间缩短28.6%;当含水量为质量分数45%时,穿透时间提前42.9%;当含水量增至质量分数60%时,CS2迅速穿透,ACF几乎不能再吸附CS2。更多还原

【Abstract】 The adsorptive performance of commercial activated carbon fiber(ACF) for CS2 was investigated and a comparison of the adsorptive performance of ACF with activated carbon(AC) and zeolites was made.The effects of the operating parameters such as CS2 concentration,flux,humidity and water content in ACF on the adsorptive performance were investigated.Results indicated that the ACF had a higher adsorption capacity of 46.5% than AC and zeolites did toward CS2.The breakthrough time decreased greatly with flow rate and CS2 concentration.The adsorptive performance deteriorated with increasing humidity and water content in the ACF.The adsorption time was shortened by 28.6% when humidity was increased to 65%.The breakthrough time was decreased by 42.9% when water content in the ACF was increased to 45%.The adsorptive capacity was negligible when water content in the ACF was increased to over 60%.更多还原
