Gas hydrates has been considered as one of potential materials for gas storage and transportation. In particular, structure-H gas hydrate has been highlighted due to its higher storage capacity and thermal stability than structure-I or structure-II hydrate. In this study, we found a new structure-H former, tert-butyl nitrite, through identifying its CH4 containing hydrate structure and guest distribution by powder X-ray diffraction and high-power decoupling 13C NMR spectroscopy. The phase equilibrium of tert-butyl nitrite + CH4 hydrate were also investigated and confirmed to be more stable than pure CH4 hydrate. With high polarity of tert-butyl nitrite expecting to improve hydrate formation kinetics, the present findings might contribute to the application of gas hydrate to natural gas storage and transportation. |
