摘要
天然气水合物又称"可燃冰",储气能力大,其生成与压力、温度、气水接触面积以及添加剂等因素有关。概述了天然气水合物生成的促进研究现状,介绍了不同类型的表面活性剂,包括阴离子表面活性剂(十二烷基苯磺酸钠SDBS、十二烷基硫酸钠SDS)、非离子表面活性剂(烷基多糖苷APG)对天然气水合物生成的影响,主要研究了不同类型表面活性剂对天然气水合物表观水合数、储气密度以及诱导时间的影响,同时分析了表面活性剂加速天然气水合物生成的机理。结果表明:不同类型的微量表面活性剂都不同程度地促进了天然气水合物的生成,改变了水合物的形成机理;探索研究新的添加剂,有着重大意义。
Natural gas hydrate is similar to ice with large storage capacity and its formation is related to such factors as pressure, temperature, water/gas contact area and additive. Summarized are current researches on natural gas hydrate formation and promotion, described are different effects of various surfactants, including anionic surfactant (SDBS and SDS) and nonionic surfactant (APG), on natural gas hydrate formation and analyzed is mechanism of surfactant which speeds up gas hydrate formation. Results show that various surfactants can promote natural gas hydrate formation to a certain extent and change natural gas hydrate formation mechanism. The researches on new additives are significant.
