ABSTRACT:
Solids are separated from solids-containing, high-boiling hydrocarbons by mixing a lower-boiling liquid diluent with the solids-containing, high-boiling hydrocarbons, clarifying the mixture to separate same into a solid-enriched phase and a low-solids liquid phase, separating the high-boiling hydrocarbons from the low-solids phase by distillation, and recovering and reusing the diluent. The high-boiling hydrocarbons can be heavy oil or heavy tar from the thermal treatment of hard coal, brown coal, tar sands, oil shale or the like.
