鼓泡塔中甲烷水合物生成现象的观测

观测了在透明鼓泡塔中运动气泡表面水合物的生成和带有水合物壳层的气泡在上升过程中表面颜色和大小的变化。结果表明，反应液体在循环和不循环的情况下，水合物在鼓泡塔内生成、存在的位置不同。通过对实验现象的观测、对气泡与水合物颗粒相互作用的分析和对甲烷溶解度与水合物中甲烷分率的对比，得出气泡表面水合物的生成是一种界面反应现象的结论，为水合物生成动力学模型的建立和水合物分离技术的工业化提供了参考依据。

PHENOMENA OBSERVATION OF METHANE HYDRATE FORMATION IN BUBBLE COLUMN

Formation and growth of gas hydrate on the surface of rising bubbles and the color and size changes of bubbles in transparent bubbling column were observed. In the course of experiments, it was found that the places of gas hydrate formation and its existing in bubble column were different under the conditions of reactant liquid recycled and unrecycled. After the interactions of bubbles with hydrate particles were analyzed and solubility of methane was contrasted with methane concentration in hydrate, it was concluded that the formation and growth of gas hydrate on surface of bubbles was an interfacial reaction, providing the reference for hydrate formation kinetics modeling and hydrate separation technique industrialization.
