【 摘 要 】

Presented work is devoted to the study of the process of decomposition of methane hydrate obtained in the presence of sodium dodecyl sulfate. It was found that the rate of dissociation increases with temperature and surfactant concentration increasing. It was found that free gas volume inside the reactor plays important role in the process of methane hydrate formation and influences on kinetics of hydrate formation and methane concentration in produced hydrate. It has been suggested that the decrease in the gas content in the resulting hydrate is associated with a decrease in the cooling efficiency with a larger reactor load and a decrease in the area of the effective cooling surface of the reactor walls and the formation of a hydrate on the reactor walls that reduces heat exchange between the remaining liquid phase and the refrigerant.
