The saturation uptake of the structure in question is 4.7 mmol g -1 , and is reached at 2 bar and 246 bar for CO 2 and N 2 , respectively. Using the complete pure component isotherms, we predict P 0 CO 2 and P 0 N 2 to be equal to 0.1 bar and 14 bar respectively for a mixture of 10% CO 2 . For a mixture of 90% CO 2 , P 0 CO 2 and P 0 N 2 are equal to 0.9 bar and 126 bar respectively.
