ABSTRACT:
Insoluble materials are separated from a coal liquefaction product having a quinoline insoluble content of greater than 15 wt. % by diluting the product with a diluent which is a solvent for the components which are quinoline soluble and benzene insoluble, with the diluent being added in an amount to provide a mixture having a quinoline insoluble content of no greater than 13 wt. %. Insoluble material is then separated by gravity settling in the presence of a promoter liquid having a 5 volume percent distillation temperature of at least 250.degree. F and a 95 volume percent distillation temperature of at least 350.degree. F and no greater than 750.degree. F, with the promoter liquid having a characterization factor of at least 9.75.
