实验研究表明,表面活性剂胶束溶液可加快水合物的形成和提高水合物的储气质量。在水合物形成体系实验中,添加了阴离子表面活性剂 (十二烷基硫酸钠 ).结果发现,合成天然气 (甲烷、乙烷和丙烷的摩尔分数分别为 92.0 5 %、4.96%和 2.99% )在无搅拌 (即静止 )的系统中可快速形成,而且极大地提高了水合物的储气能力。对水合物储气而言,十二烷基硫酸钠溶液的浓度存在一个最佳值,使水合物的储气量达到最大值.

Micellar surfactant solutions were found to increase gas hydrate formation rate and storage capacity. An anionic surfactant, namely sodium dodecyl sulfate (SDS) was used to improve hydrate storage capacity of a synthetic natural gas (mol percent of methane, ethane and propane are 92.05%,4.96%, 2.99%, respectively). Hydrate could form quickly in a quiescent system with the presence of SDS. There was a better SDS solution concentration for gas storage in hydrates.
