| Popis: | The clathrate hydrate formation from a model natural gas, i.e., a mixture of methane, ethane, and propane in a 90:7:3 molar ratio, under constant pressure was experimentally investigated, focusing on the evolution of the gas-phase composition inside the hydrate-forming reactor during each semi-batch hydrate-forming operation. In a previous study (Kobayashi, T.; Imura, N.; Ohmura, R.; Mori, Y. H. Energy Fuels 2007, 21, 545−553), we measured the evolution of the gas-phase composition during the initial period (up to ∼3 h) following the inception of hydrate formation, in which the total amount of gas uptake in the formed hydrates was limited to 0.8 times the amount of gas initially contained in the reactor. This study extended the previous study, such that we could observe the evolution of the gas-phase composition for a much longer time (up to ∼50 h) until a quasi-steady state was established inside a newly constructed gas-bubbling-type reactor equipped with a gas-phase-mixing stirrer that enabled the gas s... |
