We conclude from our present work: (1) Aqueous methanol is a practical solvent for separating the nitrogen and oxygen compounds in the naphtha and middle distillate boiling ranges. (2) Extractive distillation of the naphtha fraction and the 15 wt % lowest boiling fractions of the middle distillate with a high boiling phenolic solvent may be more economic than solvent extraction. (3) The SRC-II heavy distillate, per se, cannot be extracted with aqueous methanol but can be extracted with a dual solvent system. (4) Extraction of coal liquids with DMF may be simpler and more economic than extraction with aqueous methanol. (5) Continuous liquid extraction of coal liquids can be practiced successfully. (6) Extraction of coal liquids with water and with aqueous methanol at superatmospheric temperatures and pressures may be practical.
