Enthalpy and phase behavior of coal derived liquid mixtures: Final technical report. [Tetralin/m-cresol/quinoline]

Technical Report ·
OSTI ID:6787481

Measurements were made in a Freon 11, reference fluid, boil-off calorimeter, and an equilibrium flash vaporization apparatus, experimental systems which had already been developed. Previous studies had indicated that existing data and correlations developed for petroleum fluids are not applicable to coal derived liquids. This was due to the presence of significant concentrations of polar associating heteroatomics in the predominantly aromatic coal liquids. Thus, the ternary system was selected to include an aromatic, a basic nitrogen compound, and a cresol. Measurements were made over a wide range of temperature (200 to 700/degrees/) 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. This set of data will be useful as a standard for fitting and evaluating thermodynamic correlations and equations of state that are applicable to associating fluid mixtures, and thus to coal derived liquids. In addition efforts were and continue to be made at developing equation of state correlations which are applicable to these highly nonideal mixtures. 46 refs., 43 figs., 41 tabs.
