Abstract

Carbon dioxide hydrates were formed and dissociated in a lab-scale apparatus, filled with demineralised water and porous sediments. Two different porous media were tested; the first consists of glass beads, commonly used to reproduce marine environments during lab-scale hydrate formation experiments. Natural basaltic sand, typical of the Icelandic margins, was chosen as second sediment. The role played by the two sediments, was analysed both during the hydrate formation and dissociation processes and the results were compared among each other. In particular, the pressure – temperature values measured during the dissociation phase, were compared with the phase boundary equilibrium conditions for pure carbon dioxide hydrates, carried out in absence of any porous sediment, collected from the scientific literature.

冰岛边缘天然玄武岩多孔介质中二氧化碳水合物的形成和解离。

二氧化碳水合物是在实验室规模的仪器中形成和解离的，仪器中充满了去矿物质水和多孔沉积物。测试了两种不同的多孔介质：第一种由玻璃珠组成，通常用于在实验室规模的水合物形成实验中再现海洋环境。第二种沉积物是冰岛边缘地区典型的天然玄武岩砂。分析了两种沉积物在水合物形成和解离过程中所起的作用，并对结果进行了比较。特别是将解离阶段测得的压力-温度值与从科学文献中收集到的纯二氧化碳水合物在无任何多孔沉积物情况下的相界平衡条件进行了比较。
