Abstract
Efficient removal of propyne impurities from propylene is essential for producing high‐purity propylene. In this study, we utilize the flexible metal‐organic frameworks (MOFs) material, MOF‐508, for C3H4/C3H6 separation. Propyne (C3H4) induces a "gate‐opening" effect in MOF‐508, transitioning it from a narrow‐pore (NP) phase to a large‐pore phase at low pressure. In contrast, propylene (C3H6) only triggers this effect at a higher pressure of 0.55 bar. Notably, at 298 K and 0.5 bar, MOF‐508 adsorbs 71.9 cm³/g of C3H4, compared to just 7.9 cm³/g of C3H6. This selective adsorption significantly enhances C3H4/C3H6 separation (50/50, v/v), as further demonstrated by dynamic breakthrough experiments.
