Cage occupancies and guest-host interactions of binary gas hydrates

为了了解包合物水合物主体水笼中客体分子的分布和笼子占有率，本项目研究了以甲烷或二氧化碳为客体分子的二元气体水合物。在这方面，我们通过相衬X射线成像测量和粉末X射线结构分析对分析方法进行了优化。本文成功地对二氧化碳水合物的无损分析、丁烷甲烷混合气体水合物的晶体结构分析进行了密度估算。

To understand distributions and cage occupancies of guest molecules within host water cages of clathrate hydrate, binary gas hydrates including methane or carbon dioxide as guest molecule were investigated in this project. In this respect, we optimized the analysis method by phase contrast X-rays imaging measurement and powder X-ray structure analysis. Herein, density evaluations of the nondestructive analysis of a carbon dioxide hydrate, the crystal structure analysis of butane + methane mixture gas hydrates were successfully performed.
