Enthalpy measurement of coal-derived liquids. Quarterly technical progress report, July--September 1977. [155 to 742 degrees F and 150, 200, 500, 1000 and 1500 psia]

Coal-derived liquids are a new and vital class of industrial compounds, but have thermodynamic properties that are largely unknown and, presently, unpredictable. The objective of this research is to measure one of the most important thermodynamic properties, the enthalpy, for representative coal-derived liquids over the pressure and temperature regions most likely to be encountered in both liquefaction and processing systems. Experimental measurements were made on a distillate from a coal-derived liquid sample produced with the Synthoil process. The measurements extend from 155 to 742/sup 0/F at pressures of 150, 200, 500, 1000, and 1500 psia. Enthalpy measurements were also started on a naphtha cut from a coal-derived liquid produced by the SRC-I process. These naphtha measurements are approximately 60 percent complete.
