摘要:

我们研究了基于图的卷积神经网络方法,用于预测和排序晶体金属有机框架(MOF)吸附剂的气体吸附性能,以应用于燃烧后捕获$\textrm{CO}_2$。我们的模型是完全基于标准的结构输入文件,包含原子描述的吸附剂材料的候选人。我们构建了新的方法扩展,以匹配经典机器学习模型的预测精度,这些模型是以更高的计算成本构建的,具有数百个特征。我们的方法可以更广泛地应用于优化工业规模的气体捕获过程。

英文摘要:

We investigate the graph-based convolutional neural network approach for predicting and ranking gas adsorption properties of crystalline Metal-Organic Framework (MOF) adsorbents for application in post-combustion capture of $\textrm{CO}_2$. Our model is based solely on standard structural input files containing atomistic descriptions of the adsorbent material candidates. We construct novel methodological extensions to match the prediction accuracy of classical machine learning models that were built with hundreds of features at much higher computational cost. Our approach can be more broadly applied to optimize gas capture processes at industrial scale.
