Coal liquefaction in an inorganic-organic medium

Improved process for liquefaction of coal by contacting pulverized coal in an inorganic-organic medium solvent system containing a ZnCl2 catalyst, a polar solvent with the structure RX where X is one of the elements O, N, S or P, and R is hydrogen or a lower hydrocarbon radical; the solvent system c...

Beschreibung
Zusammenfassung:	Improved process for liquefaction of coal by contacting pulverized coal in an inorganic-organic medium solvent system containing a ZnCl2 catalyst, a polar solvent with the structure RX where X is one of the elements O, N, S or P, and R is hydrogen or a lower hydrocarbon radical; the solvent system can contain a hydrogen donor solvent (and must when RX is water) which is immiscible in the ZnCl2 and is a hydroaromatic hydrocarbon, selected from tetralin, dihydrophenanthrene, dihydroanthracene or a hydrogenated coal derived hydroaromatic hydrocarbon distillate fraction.
