摘要

沸石 13X 是捕获二氧化碳的理想候选材料。不过，该系统还需要在吸附和扩散方面进行更详细的研究。为此，我们使用无粘合剂沸石 13X（NaMSX）和二氧化碳进行了频率响应（FR）测量。为了研究它们对扩散过程的影响，对颗粒大小和样品量进行了调整。对大孔扩散进行了检测，并确定了相应的扩散系数。上述系统还用于评估内部 FR 仪器的性能。

Insights into CO2 Diffusion on Zeolite 13X via Frequency Response Technique

Zeolite 13X is an excellent candidate for the capture of CO₂. However, this system needs to be investigated in more detail with regard to adsorption and diffusion. For this purpose, frequency response (FR) measurements were carried out with binderless zeolite 13X (NaMSX) and CO₂. The size of the particles and the sample amount were modified in order to investigate their effects on diffusion processes. Macropore diffusion was detected and the corresponding diffusion coefficients were determined. The mentioned system was additionally used to evaluate the performance of the in-house FR apparatus.
