Technical Report

OSTI ID:6071093
The objectives of this research are: (1) To generate extremely pure coal liquid model compounds by zone purification and subsequent verification of their purities in order to conduct thermodynamic studies such as vapor pressures, gas solubilities, and vapor-liquid equilibria measurements. (2) To further exploit a high temperature vapor pressure apparatus to measure the vapor pressures of selected coal liquid compounds, to obtain derivative functions of the vapor pressures, and to derive heats of vaporizations therefrom. (3) To measure phase densities and apply the phase densities and vapor pressure data to obtain liquid phase fugacities. (4) To apply a high temperature, high pressure chromatography system to obtain K-values at infinite dilutions and Henry's Law Constants in volatile gas-coal liquid systems. (5) To develop generalized correlations for the predictions of thermodynamic quantities along the vapor-liquid coexistence loci such as heats of vaporization, vapor pressures, interfacial tensions, and coexisting phase densities incorporating a three parameter corresponding states correlation and renormalization group formulations. Accomplishments for the period July 1982-December 1985 are presented.
