月桂酸钠对气体水合物生成的促进作用

Promotion Effect of Sodium Laurate on Gas Hydrate Formation

以二氧化碳水合物为对象,在四种不同浓度的月桂酸钠体系中,研究了月桂酸钠对二氧化碳水合物生成的影响.结果表明:月桂酸钠能够明显促进二氧化碳水合物的生成,随着体系中月桂酸钠浓度的增加,二氧化碳水合物的生成速率加快,当月桂酸钠的浓度大于CMC浓度时,浓度的增加对二氧化碳水合物的生成速率几乎没有影响.

Carbon dioxide hydrate were produced from the anionic surfactant - Sodium Laurate water solutions of 0. 000,0. 016,0. 021,0. 026 mol/L to investigate the effect of surfactant on gas hydrate formation in a quiescent system. The results show that Sodium Laurate can markedly promote gas-hydrate growth and hydrate formation rate increases with Sodium Laurate concentration, but when Sodium Laurate concentration above critical micellar concentration（ CMC）, the increase in Sodium Laurate concentration will have little effect on promotion of gas hydrate formation rate.
