摘要: 吸附剂的孔隙结构对于有机易挥发物(VOCs)的回收利用具有显著影响。活性炭的传统筛选方法不仅需要对孔隙结构进行表征,还要实验测定相应样品吸附正丁烷的工作容量。为提高活性炭的筛选效率,结合61种活性炭的表征信息,经机器学习回归基于BP神经网络的活性炭分类模型,重复30次计算所研究活性炭吸附正丁烷工作容量的计算结果与实验值的平均偏差约为6.64%,成功建立了活性炭特征参数和吸附正丁烷工作容量之间的定量关系,这对于降低实验成本具有重要的研究意义。

Abstract: The adsorption performance of volatile organic components (VOCs) on adsorbent was strongly affected by its porous structure. The traditional adsorbent screening required not only porous characterization, but also n-butane working capacity (BWC) measurement. In order to improve the screening efficiency, the average deviation of the experimental BWC and the calculated ones obtained from the BP artificial neural network constructed by machine learning on corresponding characterizations after thirty repeats of 61 kinds of activated carbon samples was about 6.64%. It was significant to explore such quantitative relationship between feature properties of activated carbon and their related BWC, which was meaningful for the further reduction of expenditure on adsorbent screening.

Key words: amorphous materials, porous structure, quantitative structure-property relationship, butane adsorption, application of artificial intelligence algorithm
