粘胶基活性碳纤维毡吸附性能的研究

Study on adsorption capacity of viscose-based activated carbon fiber felt

研究了粘胶基活性碳纤维(VACF)对不同极性有机气体的吸附与解吸性能。结果表明:VACF对极性较大的有机气体苯饱和吸附量较大,达饱和吸附的时间较长;而对极性较小的有机气体正己烷饱和吸附量较小,达饱和吸附的时间较短。采用动态加热法,VACF对有机气体的解吸速度最快。VACF对极性大的有机气体苯最难解吸。

The adsorption and desorption properties of viscose-based activated carbon fiber （VACF） for organic gases with dif- ferent polarities were studied. The results showed that VACF had high saturated adsorption capacity for organic gas with high po- larity, benzene, and reached saturated adsorption within a long period of time, but had low saturated adsorption capacity for or- ganic gas with low polarity, n-hexane, and reached saturated adsorption within a short period of time. Dynamic heating method produced the highest desorption rate of organic gas from VACF. It was the most difficult for VACF to desorb organic gas with high polarity, benzene.
