Beschreibung
To meet the continuously rising demand for natural resources and high-value compounds, the development of new and more efficient separation technologies is important from both an economic and environmental point of view. Moreover, the detailed knowledge of adsorption phenomena can be beneficial for the development of task-specific adsorbents for gas separation processes. However, new or supplementary measurement techniques are needed to broaden the understanding of the underlying molecular mechanisms and to characterize promising materials with a fast and reliable method. Raman spectroscopy holds the potential to advance the state-of-the-art in thermophysical property research for CCS technologies in multiple ways. It can not only be utilized for fundamental research on adsorption on quasi non-porous materials due to the possibility to monitor the composition of fluid mixtures but also for the characterization of newly developed porous adsorbents.
In this context, Raman spectroscopy was explored in this work to characterize the sorption capacity of translucent porous materials and to investigate the underlying mechanisms that govern sorption processes.
