Raman spectropic Investigation of Guest Dynamics in Clathrate Hydrates: CH4, CO2, N2 in sI and sII Hydrates. |
| 초록 |
For practical applications of gas hydration in environmental and technological processes, considerable knowledge regarding the thermodynamic stability, structural analysis of hydrates and occupation behavior of a specific component of gas mixture is essential. The hydrate phase equilibria of CH4/CO2/N2 (55/40/5)+liquid solutions (water+5.56 mol% acetone) was determined in the temperature range 274 to 284 K and pressure of up to 5MPa. In addition, the compositions of hydrate phase were obtained under the following variables: (1) hydrate-forming temperature, (2) formation area of the hydrate where CH4+acetone hydrates were formed, but CO2+acetone hydrates cannot be formed (3) hydrates structure types: (a) structure I, (b) structure II. In addition, structural identification of the CH4+CO2+N2+acetone hydrates was monitored under the different acetone mol fractions [(0, 0.01, 0.03 and 0.0556) mol fraction]. Furthermore, temperature-dependent occupation behaviors of CH4 and CO2 in clathrate II hydrate cages were studied in the temperature range 140 to 260 K. |
