Comparative study on zeolites, activated carbons and metal-organic framework materials for CO2 adsorption |
| 초록 |
Benchmark adsorbents, zeolites and activated carbons with different physicochemical properties were used for the adsorption of CO2 at 25oC, and their adsorption capacities were compared to that of commercially-available metal-organic framework (MOF) materials. At a 840-Torr CO2 pressure, the uptake was measured to be 7.94 and 4.10 mmol/g for the respective NaY zeolite and MSP-20 activated carbon, while all the remaining benchmarkers showed CO2 uptakes below 3.0 mmol/g although this value was greater than that of the commercial MOFs. Neither of the specific surface area, mciro-and mesopore sizes, and pore volume were visibly associated with the indicated CO2 uptakes. Based on the isotherms collected, it was shown that the extent of CO2 adsorption with all the benchmarkers seems to be reached to an endpoint of each uphill road at pressures near 1 bar or slightly greater, suggesting that these adsorbents may have a low working capacity for pressure swing separation. |
