Wyodak coal liquefaction runs have been completed using nine different solvents derived from Wyodak coal recycle solvent from the Wilsonville, Alabama SRC plant. Results suggest that the effectiveness of the solvents studied tends to improve as the boiling range of the solvent increases. Further, mildly hydrogenated Wyodak solvents appear to be more effective than either unhydrogenated or severely hydrogenated solvent. In addition, 13 additional solvents have been prepared from a Kentucky coal-derived recycle solvent produced at the SRC plant in Tacoma, Washington; from Pittsburgh Seam coal-derived anthracene oils from the Clairton works of U.S. Steel; and from Hanna coal-derived in situ coal gasification tars produced at Hanna, Wyoming. Coal liquefaction runs have been initiated using these solvents. Open column and high-performance liquid chromatography have been used to separate monophenols from recycle solvents. Fluorescence spectroscopy has been employed for identification and characterization of the monophenols. Nitrogen type analysis shows that nitrogen compounds in coal-derived liquids contain a high percentage of quinoline types which may be difficult to remove.
