中文摘要：

为了揭示表面活性剂对气体水合物生长过程的定量影响,实验研究了十二烷基苯磺酸钠（SDBS）对R141b水合物的生长过程的影响,分析了SDBS对R141b水合反应物界面张力的影响,研究结果表明：R141b水合物生成条件下SDBS的临界胶束浓度约为400mg/kg,1.0℃400mg/kg SDBS溶液中R141b水合物的平均引导时间为3 min,水合率约为每分钟1.7%。

英文摘要：

In order to investigate the quantitative effect of surfactant on the formation process of gas hydrate,The formation process of R141b hydrate in sodium dodecylbenzenesulfonate-6 solution （SDBS） was studied and the influence of SDBS was analysed on the interfacial tension of R141b hydrate formers.The results indicate the CMC of SDBS is about 400 mg/kg under the conditions of R141b hydrate formation.The average induction time of R141b hydrate is 3 min.in SDBS solution of 400 mg/kg and formation rate is about 1.7%per minute when the temperature is 1.0℃.
