| Research Abstract |
The crystal structure of hydrocarbon hydrate was investigated by powder neutron diffraction at low temperature. We developed a closed circle refrigerator specialized for clathrate hydrate. The sample could be mounted in the refrigerator keeping below 100 K with liquid nitrogen. The lowest temperature was about 10 K in the refrigerator. We measured 4 samples (methane hydrate, mixed gas of methane and carbon dioxide hydrate, ethane hydrate and propane hydrate) with powder neutron diffractometer using by this refrigerator and clarified the difference of the crystal structure among these clathrate hydrate.
