Effect of different surfactants on methane hydrate formation
摘要
Abstract
To study the effects of different surfactants on methane hydrate formation,anionic sodium dodecyl sulfate (SDS),cationic dodecyltrimethylammonium-bromide (DTAB) and nonionic dodecyl alcohol ethoxylates (AEO) were used in methane hydrate formaiton.The effects of the properties of surfactants (such as critical micelle concentration) and wettability of surfactant solutions on inner face of reactor sidewall to methane hydrate formation was studied.The results showed that the promotion mechanism of DTAB and AEO to methane hydrate formation was micelle effects.For SDS,the hydrate formed initially at the gas/liquid/solid interline as porous structures,which could keep the continuous gas/liquid contact under the capillary effect.关键词
