Stability boundaries of gas hydrates helped by methane-structure-H hydrates of methylcyclohexane and cis-1,2-dimethylcyclohexane
TL;DR: In this article, the four-phase coexistence curves for the structure-H hydrates of methylcyclohexane and cis-1,2-dimethylcycloencylhexane in the presence of methane are measured in the temperature range 274.09-288.29K and pressure range 1.42-8.89MPa.

TL;DR: Pressure-dependent neutron scattering measurements reveal that CBCEs in plastic crystals can be attributed to the combination of extensive molecular orientational disorder, giant compressibility and highly anharmonic lattice dynamics of these materials.
Journal ArticleDOI

TL;DR: Contrary to numerous recent reports, this work shows that, below a THF mole fraction of 0.01, H(2) molecules can occupy the large cages of the THF+H( 2) structure II hydrate system and the hydrogen storage capacity was increased to approximately 3.4 wt %.
Journal ArticleDOI
Thermodynamic and Raman spectroscopic studies on H2+tetrahydrofuran+water and H2+ tetra-n-butyl ammonium bromide+water mixtures containing gas hydrates
Journal ArticleDOI
Thermodynamic stability of hydrogen ++ tetra-n-butyl ammonium bromide mixed gas hydrate in nonstoichiometric aqueous solutions
TL;DR: In this article, the three-phase equilibrium curves obtained in the present study are shifted to the low-temperature or high-pressure side from that of the stoichiometric tetra-n ǫ-butyl ammonium bromide solution.
