Abstract

Phase equilibrium data for H₂ + tetrahydrofuran (THF) and H ₂ + cyclopentane (CP) binary clathrate hydrate systems were determined from temperature and pressure measurements with a newly designed semimicro (≈ 0.78 cm³) cell. The range of conditions studied for the two systems was at pressures from (2 to 14) MPa and at temperatures from (278 to 285) K. Inclusion characteristics of the hydrogen molecules for both systems were similar according to their Raman spectra. The measured data for the H₂ + THF binary clathrate hydrate system were in agreement with some of the data in the literature. New phase equilibrium data and Raman spectroscopy analyses for the H₂ + CP binary clathrate hydrate system are reported. The dissociation enthalpies determined from data in the pressure range from (8 to 14) MPa were (212 and 220) kJ•mol^-1 for the H₂ + THF and H₂ + CP binary clathrate hydrate systems, respectively.
