摘要

本文采用多维线性回归方法研究了甲苯在活性炭(AC)样品上的动态吸附容量与几个重要特征值之间的关联。在这些特征值中,四氯化碳(CTC)吸附值与不同来源和形式的活性炭样品上甲苯吸附容量的相关性相对较强,尤其是在接触高浓度甲苯时。值得注意的是,甲苯吸附容量与 CTC 值的相关性还可以扩展到一系列其他多孔吸附剂上,这证明了 CTC 值在表征吸附行为方面的广泛适用性。在这些结果的基础上,建立了一个数学直观模型,用于预测不同条件(入口浓度、吸附时间、初始 CTC 值等)下不同交流电样品对甲苯的吸附饱和度,其准确性随后得到了实验数据的验证。因此,该方法实现了对 AC 样品以及其他多孔吸附剂吸附行为的快速准确评估。

Modelling and prediction of toluene adsorption saturation basing on characteristic values of activated carbons

Modelling and prediction of toluene adsorption saturation basing on characteristic values of activated carbons

Herein, the association between the dynamic adsorption capacity of toluene and several important characteristic values on activated carbon (AC) samples was investigated by multidimensional linear regression. Among the characteristic values, the carbon tetrachloride (CTC) adsorption value has demonstrated relatively stronger correlation with the toluene adsorption capacity on AC samples with diverse sources and forms, particularly in exposure to high-concentration toluene. Notably, the relevance of the toluene adsorption capacity to the CTC value could also be extended to a series of other porous adsorbents, which proved the wide applicability of CTC value in characterizing the adsorption behaviors. Based on these results, a mathematical and visual model was then established to predict the toluene adsorption saturation under different conditions (inlet concentration, adsorption time, initial CTC value, etc.) on diverse AC samples, of which the accuracy has later been verified by experimental data. As such, a fast and accurate estimation of the adsorption behaviors over AC samples, and possibly other porous adsorbents, was realized.
