dc.description.abstract |
In this study, the thermodynamic behaviors, storage capacity, and structural transition of the CO2 + N2 + MCP hydrates were investigated for their potential applications in hydrate-based CO2 capture and sequestration. sH hydrates can capture large-sized liquid hydrocarbon as guests in the presence of help gases such as CH4, Xe and N2. However, a controversy arose from the fact that CO2 functions as a co-guest molecule to form sH hydrate. In order to resolve the controversy, the four-phase equilibria of the CO2 + N2 + MCP+ water mixtures were measured and compared with the three-phase equilibria of the corresponding CO2 + N2 + water mixtures to investigate the enclathration of CO2 as a co-guest in sH hydrates. In addition, Raman spectroscopy and powder X-ray diffraction (PXRD) were used to verify the structural transition. Also, hydrate composition and gas consumption experiments were conducted to measure the gas storage capacity of the CO2 + N2 + MCP hydrates. From these results, we confirmed that CO2 can act as a co-guest of sH hydrates and the structural transition from sH to sI occurs in N2-rich systems. |
