Selective Adsorption of CO2 from Light Gas Mixtures by Using a Structurally Dynamic Porous Coordination Polymer


  • This work was performed in support of the National Energy Technology Laboratory’s ongoing research in CO2 capture under the RES contract DE-FE0004000 and has utilized neutron scattering facilities supported in part by the National Science Foundation under Agreement No. DMR-0454672. Reference in this work to any specific commercial product is to facilitate understanding and does not necessarily imply endorsement by the United States Department of Energy. Certain commercial materials and equipment are identified in this paper only to specify adequately the experimental procedure. In no case does such identification imply recommendation by NIST nor does it imply that the material or equipment identified is necessarily the best available for this purpose.

Flexibilität sorgt für Selektivität: Die selektive Adsorption von CO2 aus Gasgemischen mit N2, CH4 und N2O in einem dynamischen porösen Koordinationspolymer (siehe Monomerstruktur) wurde durch ATR-FTIR-Spektroskopie, Gaschromatographie und Kleinwinkelröntgenstreuung untersucht. Alle drei Techniken bestätigen eine hoch selektive Adsorption von CO2 aus CO2/CH4- und CO2/N2-Gemischen bei 30 °C und keine Selektivität beim CO2/N2O-System.
