气体水合物生成过程强化方法研究进展

全面综述了气体水合物生成过程强化技术的研究进展，分析了各种强化方法的研究现状及其优缺点. 现有的过程强化技术只针对水合反应过程，通过搅拌、鼓泡和添加化学添加剂等方式均能缩短水合物生成诱导时间，促进其生成；水合物生成过程是一个复杂的传热传质及水合反应过程，过程机理有待深入研究，需建立包括温度、压力、客体尺寸和水的状态及搅拌程度等因素综合作用下的水合物生长模型，准确揭示水合物生成过程的强化机理. 最后指出了气体水合物生成过程强化技术存在的问题和今后的研究方向.

Advances in Methods for Enhancing Formation Process of Gas Hydrate

Research advances in promotion technology of gas hydrate formation process are comprehensively reviewed, the status of reinforcing methods is summarized, and their relative merits are analyzed. The results show that the existing research of reinforcing methods was confined in hydration reaction process itself, and these methods such as stirring, bubbling and adding chemical additives could promote the formation process and shorten the induction time of hydrate formation. However, the formation process of hydrate is a complicated hydration reaction process with heat and mass transfer. The existing research has failed to accurately reveal the process mechanism. It is necessary to establish growth model of hydrate by putting the influential factors such as temperature, pressure, size of the object, state of water and degree of agitation into consideration, and accurately reveal the promoting mechanism of hydrate formation process. Finally, existing problems and future research direction in promotion of gas hydrate formation process are also pointed out.
