表面活性剂促进气体水合物生成的研究
Research in Surfactant Effect on Promoting Gas Hydrates Formation

天然气水合物被公认为21世纪的重要后续能源，其生成与压力、温度、气水接触面积以及添加剂等因素有关。文章概述了表面活性剂的基本性质，并从其改变反应液的表面张力、形成胶束、改变水合物形貌等方面总结了表面活性剂对促进水合物生成的影响，提出了其促进水合物生成的机理。对于未来的研究，我们不仅要观察水合物的形态，也要从水合物膜的内部结构分析表面活性剂对水合物的生成影响，为水合物生成机理形成统一的认识和气体水合物进一步发展提供参考。
Nowadays, natural gas hydrates are recognized as an important future energy in 21 Century. Pressure, temperature, the contact area of gas and water, surfactant and other factors affect its formation. The basic properties of the surfactant are introduced in the present paper, and the effects of surfactant on the formation of hydrates are summarized from the changes of surface tension of liquids for gas hydrates formation, micelle formation and the hydrate morphology. The mechanism of surfactant promoting gas hydrates formation is then put forward. In order to form a unified understanding on hydrate formation mechanism, the hydrate form is not only observed, the influence of the surfactant on the formation of the hydrate is also analyzed from the internal structure of the hydrate film for the future research
