气体水合物生成特性实验研究

实验研究了添加剂对甲烷气体水合物形成过程的影响。发现微量的表面活性剂降低了甲烷气体水合物在静止反应器中形成的诱导时间，并使水合物快速形成和生长，提高了水合物形成过程中的填充密度。阴离子表面活性剂（十二烷基硫酸钠）对水合物生长的促进作用比非离子表面活性剂（烷基多糖苷）强。液态烃环戊烷降低了水合物形成的诱导时间，但环戊烷不能提高水合物的填充密度。 <hr /> The effect of additives on methane gas hydrate formation was tested. The induction time of methane hydrate formation was reduced, gas hydrate could grow rapidly, and the methane consumption was improved during hydrate formation in a quiescent cell with micella surfactants. The effect of an anionic surfactant （ sodium dodecyl sulfate） on gas hydrate formation is more pronounced compared to a nonionic surfactant （dodecyl polysaccharide glycoside）. Cyclopentane reduced the induction time of hydrate formation, but could not improve the methane consumption during gas hydrate formation in a quiescent cell.
