Table 1. Physical Properties of Support Materials and Adsorbents.
| support materials | MIL-101(Cr) | γ-Al2O3 |
|---|---|---|
| particle size, [μm] | ∼0.544 | 6.9a |
| pore volume, [cc/g] | 1.84 | 0.95 |
| pore size (mode), [nm] | 2.4 | 16.1 |
| BET surface area, [m2/g] | 3270 | 153 |
| amine (TEPA) loadings, [wt %] | 30 | 20 |
| powder sorbents | MIL-101(Cr)_TEPA(30) | Al2O3_TEPA(20) |
| pore filling, [ %] | 25.4 (by N2 physisorption) | 27.6 (by N2 physisorption) |
| 23.3 (by calculation) | 26.5 (by calculation) |
Mean particle size was determined based on SEM images (Figure S2).
