多孔介质中气体水合物的分解动力学研究现状

Research on the Kinetics of Gas Hydrate Decomposition in Porous Media

目前关于水合物的相平衡理论、热力学性质、生成预测方法及其结构的研究已经相当深入;而关于其分解过程的研究相对来说起步较晚。国内气体水合物分解动力学的研究基本上还处于空白状态,国外也是在1987年才开始。但是从实际生产的角度考虑,气体水合物分解动力学的研究是很有实际意义的。文章试图对近年来国外在多孔介质中气体水合物分解动力学研究方面取得的进展做出分析和评价,并提出今后的发展方向。

The research about gas hydrates phase equilibrium, thermodynamic properties, methods of predicting their formation and structures were fairly fruitful, but it was later to study about the process of their decomposition. However, works on the kinetics of gas hydrates＇decomposition was rarely reported until the year of 1987. With the view point of practical pro- duction, researches on the kinetics of gas hydrates＇decomposition were of tremendous significance absolutely. In this paper, the progress in the kinetics of gas hydrates decomposition in porous media was described, and the future development direction of the research was also pointed out.
