Enthalpy and phase behavior of coal derived liquid mixtures: Technical progress report for the period July-September 1987
The objectives of this program are to study the enthalpy and phase behavior of a selected ternary model compound system, representative of interactions present in coal derived liquids. Measurements were made in a Freon 11 reference fluid boil-off calorimeter, and an equilibrium flash vaporization apparatus. The ternary system included an aromatic, a basic nitrogen compound, and a cresol: the m-cresol/quinoline/tetralin ternary mixture. Measurements were made over a wide range of temperature (200 to 750/sup 0/F) and pressure (20 to 1500 psia), for the three pure compounds, the three binary mixtures and selected compositions of the ternary. Both enthalpy and phase behavior measurements were made. Equation of state parameters obtained from binary enthalpy data are more reliable when extrapolated to the ternary system, than parameters obtained from vapor liquid equilibrium data. Furthermore, the more complex mixing rules generally gave poorer predictions when extrapolated to ternary systems. 17 refs., 7 figs., 4 tabs.
