静态体系生成甲烷水合物是个缓慢的、不完全的过程。即使使用表面活性剂也不能实现反应物的1 0 0 %转化。本文讨论了在静态反应停止后,使用系统温度振荡的方法来促进水合反应的继续进行,直至完全转化。在系统温度从-1 0～4℃之间周期振荡时,原本停滞的水合反应在水的相变温度附近又开始发生反应,由于水合物合成时铠甲效应的存在,水在样品中的过冷度达到1 0℃左右。文中对样品的热物性测试表明,在经过几个温度变化周期后,反应非常完全,反应器中样品是1 0 0 %的甲烷水合物。
Static system to generate methane hydrate is a slow, incomplete process. One hundred percent conversion of the reactants was not achieved even with the use of surfactants. This article discusses the use of system temperature oscillations to facilitate the continuation of the hydration reaction until the complete conversion after the static reaction has ceased. When the system temperature oscillates from -1 0 to 4 ° C, the originally stagnant hydration reacts again near the water’s phase transition temperature. Due to the armor effect during the hydrate synthesis, the water is too cold in the sample Degree reached about 10 ℃. The thermophysical properties of the samples in this paper show that after several cycles of temperature cycling, the reaction is complete and the sample in the reactor is 100% methane hydrate.
