The present study explores distillation as a separation method for recovery of lignin-derived chemicals from biocrude. The biocrudes used were relatively thermally stable and distillable; they were produced from catalytic pyrolysis with a non-zeolite, alumina-based catalyst. Gas chromatography-mass spectrometry (GC-MS) analysis indicated that the biocrude contained reasonable amount of lignin-derived compounds. The distillation studies were performed with a laboratory distillation unit (PETRODIST 300 CC) and the biocrude were fractionated into four distillate cuts: Cut 1 (IBP-110 °C), Cut 2 (110-200 °C), Cut 3 (200-300 ° C), and Cut 4 (300-400 °C). The yields, physicochemical properties, and chemical composition of the fractions as well as the overall distillation separation efficiency will be discussed.
