โฆ Synopsis
Coal liquefaction products from the Hcoal and the Wilsonville Integrated two-stage liquefaction processes were separated into narrow-boiling distillates. The Wilsonville product was from the first stage. Information resulting from elemental analysis, proton nuclear magnetic resonance ('H n.m.r.), low-voltage, highresolution mass spectrometery (LVHRMS), infrared spectroscopy (i.r.) and open-column preparative liquid chromatography were obtained for each distillate. The analytical data were used to estimate the concentrations of the major functional groups in the distillates. The results indicated that the structure and functionality of the molecular constituents of the two sets of distillates boiling in the same temperature range were similar. Structural differences appear to be primarily related to the concentrations of alkylated aromatics and saturates.

Critical properties ofnarrow boiling and wide boiling coal distillates were estimated using correlations and a group contribution method. The critical property estimates were compared with critical properties regressed from hydrogen solubility data. The correlations yielded critical temperature pred
