To assess performance of CALF-20 within our framework, we employ the experimental adsorption data for CO2 and N2 by Lin et al. . Figure in SI demonstrates that our molecular simulations are in a good agreement with the experimental data for CALF-20, which also gives some reassurance for the accuracy of the predictions based on the current force field for other similar materials. The experimental data shows slightly higher CO2 adsorption, and to be on the conservative side and assess CALF-20 under the most realistic conditions, we use the experimental data to construct the DSL models required for the process modeling. The results of the process simulations are shown in Figure in green. According to this figure, CALF-20 sits on the edge of the cloud of points associated with the group of 13X zeolites. While somewhat underwhelming, this is not inconsistent with the previous studies of the CALF-20 process performance. In particular, Nguyen et al. used extensive experimental data and a process model for 4-step vacuum swing adsorption with light product pressurization to show that in the purity-recovery coordinates the performance of CALF-20 is very similar to that of 13X. It seems, therefore, that the primary appeal of CALF-20 for carbon capture is due to its unique hydrophobic nature in comparison with 13X.
