Research Abstract

All patterns of natural gas hydrates found under marine sediments were first reproduced by model experiments using the mixture of THF water solution and glass beads. The hydrate patterns were found to be classified in a diagram as a function of growth rate of hydrates and the mixing ratio between two diameters of glass beads. Qualitative model of formation mechanism of hydrate patterns were proposed. In addition, the diffusion effects of guest molecules were clarified by the experiments using dilute THF water solution in glass beads and the experiments in THF/water concentration boundary.
