摘要
为了深入探究活性炭的含水量对其吸附VLA中丙酮气体的影响,本文通过对比不同含水量活性炭的丙酮动态吸附性能,结果显示,丙酮在活性炭上的穿透时间随着其含水量的增加而缩短,床层利用率下降;通过Thomas和Yoon-Nelson模型拟合结果表明,两个模型对含水量低的活性炭丙酮穿透曲线拟合结果较好;活性炭的吸附量随着含水量的增加而减少,而其丙酮的吸附速率则是先随着含水量的增加而增加,当含水量超过20%后,活性炭的丙酮吸附速率下降,表明工业炭床中活性炭含有一定的水量有助于提升其丙酮回收效率。
The present work mainly studied the influence of the content of water on the acetone absorption of activated carbon. The results showed that breakthrough time of activated carbon was short with the increase of water content and the utilization ratio of absorption bed decreased. The fitting results of Thomas and Yoon-Nelson models showed that the breakthrough curve of acetone of activated carbon with low water content can be well fitted with the both of models. The absorption capacity of activated carbon was decreased with the increase of water content. However, the absorption rate of acetone was increased at first. When the water content exceeded 20%, the absorption rate of acetone declined. This indicated a certain content of water can benefit the acetone recycle of activated carbon.
