To explore the liquefaction behaviors of low-rank coal vitrinite, the transformations accompanying vitrinite pyrolysis were examined at 10°C per hour between 350 and 520°C. Structural characterization was every 10°C for FTIR and every 20–30°C for 13C NMR and chemical analysis. The gaseous yield of C1–C5 was evaluated by gas chromatography (GC). From the transformations, identified by these various...
