Enthalpy and phase behavior of coal derived liquid mixtures. Technical progress report, October-December 1984
On July 15, 1984, work was initiated on a program to study the enthalpy and phase behavior of coal derived liquid model compound mixtures. During the second quarter efforts were limited to ordering and installing equipment to improve the operability of the calorimeter and phase behavior system. The program is now up to full staffing levels and data collection will begin this next quarter. 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 will be made in a Freon 11 reference fluid boil off calorimeter, and an equilibrium flash vaporization apparatus. These experimental systems have already been developed. Previous studies have indicated that existing data and correlations developed for petroleum fluids are not applicable to coal derived liquids. This is due to the presence of significant concentrations of polar associating heteroatomics in the predominantly aromatic coal liquids. Thus, the ternary system will include an aromatic, a basic nitrogen compound, and a cresol. It is presently planned to study the tetralin/quinoline/m-cresol ternary mixture. Measurements will be made over a wide range of temperature (200 to 700/sup 0/C) and pressure (20 to 1500 psia), for the three pure compounds.
