ZrBDC-Based Functional Adsorbents for Small-Scale Methane Storage Systems

Figure 12

Temperature dependence of the differential molar isosteric enthalpy of the ZrBDC-CH4 adsorption system at different values of methane adsorption, mmol/g: 0.1 (1), 0.5 (2), 0.8 (3), 1 (4), 1.4 (5), 2 (6), 2.5 (7), 3 (8), 3.5 (9), 4 (10), 5 (11), 6 (12), and 7 (13). The results of calculations are shown by symbols; the lines are the spline approximation.
