A plot showing methane gas uptake (mol/mol-H2O) in hydrates at various initial gas pressures. The solid line is the computed gas uptake with small cage (512) occupancy reported by Yoon [43]. Symbols (■) and (●) represent gas uptake values with 60 and 185 mL of aq-THF solution in the reactor. (★) symbols are used to depict the similar observations with lesser (32.5 mL) amount of solution for hydrate formation (Ref. [39]). The dotted grey lines are guides to the eye.
