摘要
综述了天然气水合物中甲烷的置换反应的研究进展,比较了传统置换法与CO2置换法的优缺点,论述了CO2置换法尤其是CO2乳化液法的优越性。CO2乳化液具有更高的反应温度以及更好的传导率和扩散性,在置换反应中起到了强化作用,增加了CH4从水合物中的释放,提高了置换的反应速率,同时乳化液的热可以使热源增强,从而使置换反应得到进一步强化。
The research progresses in replacing methane out of natural gas hydrate were summarized. A comparison was made between the carbon dioxide replacement method and the conventional replacement method. The superiorities of the carbon dioxide, especially carbon dioxide emulsion replacement method over the conventional replacement method were described. The higher replacing temperature and the better conductivity and diffusibility of carbon dioxide emulsion enhanced the replacement, improved methane releasing from hydrate, and increased the replacing rate, while the heat from the emulsion enhanced the heat source which furthermore enhanced the replacement.
