| Abstract: | Basic thermodynamic properties of coal liquefied oil were analyzed, with measuring methods and some correlations about basic thermodynamic properties of petroleum, measuring methods and correlations about basic thermodynamic properties of coal liquefied oil were studied.The measurement of vapor pressure, calculating of vapor-liquid phase equilibrium constant and appraising calculating process of vaporization enthalpy of coal liquefied oil were detailedly discussed. Finally, the best way of measuring these properties was obtained. In addition, appraising calculating of critical properties of coal liquefied oil fractions were simply outlined. |
