| 中文摘要 | gas hydrate formation experiments were performed using methane in the presence of tetrahydrofuran (thf) in aqueous solution in a transparent bubble column in which a single pipe or a sintered plate was used to produce bubbles. the mole fraction of thf in aqueous solution was fixed at 6%. the hydrate formation kinetic behaviors on the surface of the rising bubble, the mechanical stability of hydrate shell formed on the surface of the bubble, the interactions among the bubbles with hydrate shell were observed and investigated morphologically. the rise velocities of individual bubbles with hydrate shells of different thickness and the consumption rates of methane gas were measured. a kinetic model was developed to correlate the experimentally measured gas consumption rate data. it was found that the hydrate formation rate on the surface of the moving bubble was high, but the formed hydrate shell was not very easy to be broken up. the bubbles with hydrate shells tended to agglomerate rather than merge into bigger bubble. this kind of characteristic of hydrate shell hindered the further formation of hydrate and led to the lower consumption rate of methane. the consumption rate of methane was found to increase with the decrease of temperature or increase of pressure. the increase of gas flux led to a linear increase in consumption rate of methane. it was demonstrated that the developed kinetic model could be used to correlate the consumption rate satisfyingly. |
