Abstract
High Resolution Image Download MS PowerPoint Slide The separation and purification of methane from natural gas are crucial chemical processes. Herein, we report a Zn-cluster-based MOF (SDMOF-3), enabling the efficient separation of mixed low-carbon alkanes. The unique Zn clusters in the MOF enhance its interaction with hydrogen atoms in alkanes, thus realizing the separation of saturated light alkanes. Single-component gas adsorption tests revealed that SDMOF-3 exhibits significantly higher affinity for C 3 H 8 compared to CH 4 and C 2 H 6 at 298 K. Dynamic column penetration experiments with mixed gases demonstrated the excellent separation performance of SDMOF-3 for separating C 3 H 8 and C 2 H 6 from CH 4 .
