Adsorptions studies with CO2 at 195 K – theory and practice
Sorption studies with CO2 are still in the spot light of current research projects. Not only because of climate relatated investigations but also to characterise nano-sized and porous materials. Close to real-life conditions of CO2 adsorption of gas mixtures are typically gained with dynamic method methods, such as breakthrough curves. However, single component isotherms are mostly collected via static manometric methods. Despite the fact that is common practice, one might varying characteristic data. One reason might be the fat that CO2 does not form a liquid phase under norm conditions.
Within this study we aim to show:
- an easy way to conduct CO2 measurements
- the nature of the adsorbed phase using the mesoporous model material MCM-41
- substance parameters for CO2
