a McCabe–Thiele diagram for C3H6/C3H8 separation by FDC–4a at 300 K, with the dashed line representing the theoretical behavior of showing no selectivity. The inset is the enlarged Y-axis showing the C3H6 fractions in the adsorbed phase. b The correlation between C3H6 concentration in the feed gas and the separation factor for FDC–4a. c The breakthrough curve of an equimolar C3H6/C3H8 mixture (total flow rate of 4.0 and 10.0 mL min−1, respectively) on FDC–4a at 300 K. C and C0 are the concentrations of each gas at the outlet and inlet, respectively. d The breakthrough curves for a cycling test of an equimolar C3H6/C3H8 mixture (total flow rate of 4.0 mL min−1) on FDC–4a at 300 K.
