| 英文摘要 | It can be foreseen that the global demand for natural gas (NG) will show an increase trend in the upcoming decades. Solidified Natural Gas (SNG) having a high energy density provides an alternative solution for the storage and transportation of NG. In this study, our focus lies on investigating the impact of 1,3-dioxane and Ltryptophan on mixed CH4/dioxane hydrate formation from multiple perspectives including thermodynamic, Raman spectra, and kinetics. The thermodynamic experimental results confirmed that the mixed CH4/dioxane hydrate can form at a moderate conditions and shows high dissociation enthalpies. A thermodynamic model based on van der Waals and Platteeuw model was applied for predicting equilibrium conditions of the Hydrate-Liquid-Vapor system, yielding an average absolute deviation ranging from 1.7% to 3.9%. Raman spectra results revealed that there is a two-stage growth mechanism for mixed CH4/dioxane hydrates. Kinetic results demonstrated that the system of CH4/5.56 mol% dioxane/water shows the highest gas uptake of 91.1 (+/- 0.5) v/v at 287.15 K and 10.0 MPa, compared to other systems. Moreover, the addition of 1000 ppm L-tryptophan can reduce the time to reach 90% uptake (t90), showing a value of 19.9 (+/- 1.8) minutes. The findings derived from this research are instrumental in developing the SNG technology. |
