| Research Abstract |
Thermodynamic behavior of binary fluid systems including hydrogen is complicated, and the systems with hydrocarbons and carbon dioxide have the critical curve diverging to a high pressure region, which are classified into Type III. In this study, Peng-Robinson equation of state (PR EOS) is adopted for the hydrogen binary systems with methane, ethane, propane, and carbon dioxide, and the mixing parameter was determined by fitting only the critical point data based on the corresponding states principle. Nitrogen + carbon dioxide system is also estimated to be classified into Type III, and behavior of the system in the supercritical region was experimentally observed in various temperatures and pressures.
