Summary: | The metal-organic framework Mg sub(2)(dhtp) with the linker dihydroxyterephthalate is known as MOF-74 or CPO-27. Mg sub(2)(dhtp) has been synthesized as powder to measure breakthrough curves in a fixed-bed adsorber and adsorption isotherms, and as a supported thin membrane layer for permeation studies. The measurement of the breakthrough curves of the binary propylene/propane mixture shows that separation with the fixed bed adsorber is possible. Propylene shows a higher affinity to Mg sub(2)(dhtp). Although the single gas propane flux is slightly higher than the one of propylene, the binary propane/propylene mixture is not separated.Original Abstract: Die metallorganische Geruestverbindung Mg sub(2)(dhtp) mit dem Linker Dihydroxyterephthalat ist als MOF-74 oder CPO-27 bekannt. Mg sub(2)(dhtp) wurde in Pulverform fuer die Messung von Durchbruchskurven im Festbettadsorber und Adsorptionsisothermen sowie als getraegerte duenne Membranschicht fuer Permeationsmessungen synthetisiert. Die Messung der Durchbruchskurven des binaeren Propylen/Propan-Gemisches zeigt, dass eine Trennung im Festbettadsorber moglich ist. Es zeigt sich hier eine hohere Affinitaet des Propylens zum Adsorbens Mg sub(2)(dhtp). Obwohl der Einzelgasfluss von Propan hoher als der von Propylen ist, weist die Mg sub(2)(dhtp)-Membran fuer das binaere Gemisch kein Trennverhalten auf. |
