Under subcontract from CONSOL Inc. (US DOE Contract No. DE-AC22-89PC89883), the University of Pittsburgh studied the use of ultraviolet resonance Raman (UVRR) spectroscopy for the characterization of coal liquefaction resids. This study suggests that with further development the UVRR spectroscopy method may prove useful for the examination of the aromatic and unsaturated species in distillation resid materials derived from direct coal liquefaction. The technique, which was previously used for the examination of polycyclic aromatic hydrocarbons (PAH) in biomedical materials, petroleum, and polymer systems, was applied to the tetrahydrofuran (THF)-soluble portion of six 850{degrees}F{sup +} distillation resids. The results of this study indicate that the UVRR method may, with additional development, become a useful tool for the analysis of the PAHs in coal-derived materials.
