不同组成添加剂对甲烷水合物生成的影响

Effect of additive with different component on methane hydrate formation

在1L的半连续搅拌槽式反应器中,研究了添加剂十二烷基硫酸钠、草酸钾和草酸钾与十二烷基硫酸钠复合对甲烷水合物生成过程的影响.结果表明:十二烷基硫酸钠的作用优于草酸钾、草酸钾与十二烷基硫酸钠的复合.甲烷水合物储气量达到159.1 Vg.V-H1,其生成速率达到0.43 Vg.V-H1.min-1,优于文献报道结果.

In 1L semi-continuous tank reactor, researches the effects of sodium dodecylsulfate, potassium oxalate, mixture of sodium dodecylsulfate and potassium oxalate on formation process of methane hydrate. Results show the effect of sodium dodecylsulfate is better than the effects of potassium oxalate, mixture of sodium dodecylsulfate and potassium oxalate. Gas storage capacity of methane hydrate arrives 159.1 Vg· VH^- 1, formation rate of methane hydrate arrives 0.43 Vg· VH^- 1· min^- 1, they are better than the results reported in references.
