  • Solid-state NMR Studies of Host–Guest Interaction between UiO-67 and Light Alkane at Room Temperature
    The Journal of Physical Chemistry C, 2017
    Co-Authors: Anmin Zheng, Xiaolong Liu, Feng Deng
    Abstract:

    The host–guest interaction between adsorbent and adsorbate plays essential roles in the gaseous storage and chemical separation using metal–organic frameworks (MOFs). Solid-state NMR spectroscopy was employed to explore the interactions between light alkanes including Methane, ethane, propane and a representative MOF, UiO-67 at room temperature. The existence of host–guest interaction between light alkanes and UiO-67 framework is clearly evidenced from two-dimensional 1H–1H spin diffusion homonuclear correlation and 1H–13C HETCOR with spin diffusion experiments. By fitting the spin diffusion buildup curves, it is found that Methane is more readily to diffuse to the UiO-67 framework compared to ethane and propane. Moreover, the spin diffusion MAS NMR results reveal that Methane is mainly adsorbed neighboring the metal cluster, whereas propane and ethane are preferentially present nearby the site away from the metal cluster due to the steric hindrance effect. The results presented herein would provide a bet...

  • Enthalpy of Vaporization Measurements of Liquid Methane, Ethane, and Methane + Ethane by Differential Scanning Calorimetry at Low Temperatures and High Pressures
    Journal of Chemical & Engineering Data, 2017
    Co-Authors: Tauqir H. Syed, Thomas J. Hughes, Eric F. May
    Abstract:

    This paper presents measurements of the enthalpy of vaporization of pure and binary hydrocarbon fluid mixtures using a commercial differential scanning calorimeter (DSC). The DSC was modified to allow the direct measurement of enthalpies of vaporization, ΔvapH, at temperatures as low as 80 K and pressures as high as 10 MPa and was tested by measuring enthalpies of vaporization, both under vaporization and under condensation, for pure Methane at T = (118, 123, 128, and 133) K and pure ethane at T = (208 and 213) K. The measured values had relative deviations of less than 3% from recommended literature values. Then ΔvapH was measured for mixtures of Methane + ethane, Methane + propane, and ethane + propane at various temperatures by both condensing and vaporizing samples. In contrast to the pure fluid measurements, the measurement pathway affected the value of ΔvapH obtained because the condensation occurred along a constant composition pathway whereas the composition varied during vaporization as a result ...
