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

Figure 10

Deliverable specific volumetric methane capacities for the ANG system with as-synthesized powder ZrBDC (a), shaped ZrBDC-F (b), and ZrBDC-PVA (c) versus pressure at the temperature, K: 253 (1), 273 (2), 293 (3), 303 (4), 313 (5), 323 (6), and 333 (7). Solid lines in (a) and (b) show the results of calculations by Eq. (5) using the methane adsorption data. Symbols in (c) show the results of measurements on the experimental ANG bench with the adsorber loaded with the ZrBDC-PVA pellets; solid lines in (c) are spline-approximation. Dashed lines show the dependence for a CNG system. The error bars are 5%.
