We present the development and application of X-ray Computed Tomography (CT) for the determination of the adsorption properties of microporous adsorbents and the study of breakthrough experiments in a laboratory fixed-bed adsorption column. Using the model system \(\text {CO}_2/\text {helium}\) on activated carbon, equilibrium and dynamic adsorption/desorption measurements by X-ray CT are described, and the results are successfully compared to those obtained from conventional methods, including the application of a one-dimensional dynamic column breakthrough model. The study demonstrates the practical feasibility of applying X-ray CT to measure internal and transient concentration profiles in adsorbent systems on the length-scales from a single adsorbent pellet to a packed column.

我们介绍了X射线计算机断层扫描（CT）在微孔吸附剂吸附性能测定中的应用和在实验室固定床吸附柱上的突破性实验的研究。使用活性炭上的模型系统\（\ text {CO} _2 / \ text {helium} \），描述了通过X射线CT进行的平衡和动态吸附/解吸测量，并将结果成功地与传统方法进行了比较。方法，包括应用一维动态色谱柱突破模型。这项研究证明了使用X射线CT在从单个吸附剂颗粒到填充柱的长度尺度上测量吸附剂系统内部和瞬时浓度分布的实际可行性。
