Research and development of an advanced process for the conversion of coal to synthetic gasoline and other distillate fuels. Quarterly technical progress report No. 7, October-December 1978

Technical Report ·
OSTI ID:5514604

The present experimental work on the extraction of the coal liquids and the different distillate fractions has demonstrated that aqueous methanol is a practical solvent for separating the nitrogen and oxygen compounds in the naphtha and middle distillate boiling ranges. The naphtha hydrocarbons are lighter than the solvent and the middle distillate hydrocarbons, particularly those in the 85% higher boiling fraction, are heavier than the solvent and the best equipment performance will be obtained by extracting these fractions separately. Extractive distillation of the naphtha fraction and the 15% lowest boiling fraction of the middle distillate with a phenol solvent may be more economic than the solvent extraction of the lower density hydrocarbons.
