✦ Synopsis

Coal liquids from five major processes: Synthoil, HRI H-Coal, FMC-COED, PAMCO SRC, and Catalytic Inc. SRC have been separated reproducibly, in high yields (94-99%), into five fractions by solvent fractionation. The coal liquids are first separated into three fractions: pentane-soluble; pentane-insoluble and benzene-soluble (crude asphaltene); and benzene-insoluble. The pentanesoluble fraction is further separated into a liquid propane-soluble fraction (oil), and a liquid propaneinsoluble fraction (resin). The benzene-insoluble fraction is further separated into a carbon disulphidesoluble fraction (carbene), and carbon disulphide-insoluble fraction (carboid).
