COAL LIQUEFACTION USING HIGH AND LOW BOILING SOLVENTS

First and second slurries of a particulate coal are formed with low and high boiling fractions of a coal-derived solvent boiling within the range from 300 DEG to 1,000 DEG F., the cut point of the two fractions being from about 500 DEG F. to about 600 DEG F. The slurries are separately liquefied, pr...

Beschreibung
Zusammenfassung:	First and second slurries of a particulate coal are formed with low and high boiling fractions of a coal-derived solvent boiling within the range from 300 DEG to 1,000 DEG F., the cut point of the two fractions being from about 500 DEG F. to about 600 DEG F. The slurries are separately liquefied, producing a higher total cylcohexane conversion of the coal than if the coal had been slurried instead in the total coal-derived solvent and liquefied under like conditions.
