Thermodynamic properties for supercritical coal conversion: Quarterly progress report, 10/1/86-12/31/86. [In supercritical states]

Technical Report ·
OSTI ID:6934896
This quarter we completed several runs on the medium temperature solubility apparatus with supercritical butane and dodecahydrotriphenylene. The high temperature solubility apparatus is a relatively new unit capable of running solvents to temperatures of 350/sup 0/C. Several sets of consistent data were obtained for dihydrodibenzophenazine in supercritical ethanol with this apparatus. An isotherm at 275/sup 0/C is shown in Figure 1. High temperature supercritical solvents like butane and ethanol show significant potential for coal processing applications. Experiments with a variety of solvents, solutes, and entrainers will aid in the development of a better understanding of supercritical fluid phase behavior. Construction of the new solubility apparatus is complete and initial testing is in progress. Physical construction of the fluorescence spectroscopy apparatus is complete. Adjustment and testing are in progress. 1 fig.
