In the ethylene model, geometric features have the highest importance at 26%. Geometric features are followed closely by metal-centered RACs and full-SBU RACs at 25% and 23%, respectively. Olefin adsorption in metal-containing sorbents is well-documented to be highly influenced by the metal due to interactions between the metal and the p-bond of the adsorbate. Linker RACs and process features have the lowest overall importance at 13% each. Despite having a lower overall importance for a feature class, temperature and pressure are the two most important individual features, underscoring the importance of bulk gas chemical potential to adsorption. The process features may be more important in the ethylene model than the ethane model because ethylene will often have a higher heat of sorption, making ethylene adsorption more sensitive to changes in temperature and/or pressure. Geometric features compromise four of the ten most important features, with metal-centered RACs and full-SBU RACs comprising two each of the remaining four spots.
