摘要：

以CO2置换天然气水合物中CH4是一种集温室气体隔离和清洁能源开采于一体的方法，其关键是提高置换率和强化置换动力学。该研究以不同质量比的O/W型CO2乳状液注入天然气水合物中，经过24~96h的置换，得出的置换结果表明，质量比为90∶10的CO2乳状液在CO2水合物能稳定存在、CH4不能稳定存在且CO2呈液态的温度压力条件下，置换反应效果最好，同等温度压力条件下置换效果比纯液态CO2的置换效果好。

Abstract:

Replacing methane in gas hydrate with carbon dioxide is a method to exploit natural gas hydrate that combines greenhouse gas sequestration and clean energy source,the key of which is the improvement of replacement rate and enhancement of the kinetics.In this research,carbon dioxide emulsions with different gravity ratio of  CO2 and CH4 were injected into natural gas hydrate.It was shown,after replacement of 24-96 hours,the best result would be obtained when reacting under the condition of CO2 ′ SHZ and beside CH4 ′SHZ,with emulsion′s gravity ratio 90∶10,and the replacing result of  CO2 emulsion would be better than that of liquid CO2 .

Key words: CO2 emulsion, Replacement, Natural gas hydrate, Kinetic
