多孔介质中二氧化碳水合物生成的实验研究

Experiments on The Formation of CO_2 Hydrate With Porous Media

以多孔介质为载体,将CO2以水合物的形式固定于海底,可以减缓温室效应。CO2水合物在多孔介质中与在纯水溶液中的生成条件有很大的不同,研究了在小型CO2气体水合物实验系统中,多孔介质中CO2水合物的生成特性,探讨了温度和压力对多孔介质中CO2水合物生成特性的影响。

It can slow down the greenhouse effect that CO2 is fixed in the porous media of sea bottom in the form of hydrate. There are many differences of CO2 hydrate formation under the condition of pure water or porous media. An experimental in- strument is designed to study the formation behaviors of CO2 hydrate in the porous media. With the experimental data, fac- tors affecting the experimental results, including temperature, pressure and particle size, are in turn discussed.
