中文摘要：

采用3种不同的活性炭纤维，考察了 VOCs 种类、VOCs 浓度以及床层温度对活性炭纤维吸附 VOCs 性能的影响，并采用电致热脱附技术进行再生研究.结果表明，甲苯浓度对吸附推动力影响较大，在高浓度下，可使吸附容量达到434.8mg/g.活性炭纤维吸附甲苯受温度影响较小，在60℃下仍然具有288.6mg/g 的吸附容量.电致热脱附电压越大，活性炭纤维升温速率越快，脱附效率越高，经过100min 即可完全脱附.经过4次吸脱附循环，活性炭纤维仍有较好的吸附效果，饱和吸附量能达到原有吸附量的80%以上.

英文摘要：

The effect of adsorption conditions such as VOCs type, concentration and bed temperature on adsorption ability were investigated over the ACF. Higher concentration of VOCs resulted in higher adsorption capacity, and the adsorption capacity under 12g/m3 reached 434.8mg/g of toluene. The adsorption of toluene on ACF was less affected by temperature which adsorption capacity still remained 288.3mg/g even at 60℃. The higher the voltage of electro-thermal desorption, the faster the ACF heating rate, and the higher the desorption efficiency, what’s more, toluene was fully desorbed after 100minutes. In addition, ACF still had good adsorption performance after four cycles, saturated adsorption amount could attain more than 80% of the original adsorption quantity.
