| Outline of Final Research Achievements |
Accurate thermodynamic properties of hydrogen mixtures are essential in the hydrogen society. Binary systems of hydrogen + hydrocarbons or carbon dioxide have a discontinuous critical curve that diverges to a high pressure region, and are classified as Type III, whose behavior is far different from that of pure fluids. In this study, a saturated density and PVTx properties of hydrogen mixtures have been accurately measured. The phase boundary behavior of ternary mixtures including hydrogen calculated from an equation of state was discussed.
