ABSTRACT:
A process is disclosed for the production of hydrogenated aromatic compounds and mixtures thereof by thermal treatment of aromatic oils or mixtures, derived from coal or petroleum, wherein the improvement over the prior art resides in thermally treating aromatic oils of boiling range 280.degree.-450.degree. C., with residues from the processing of liquid coal conversion products and/or petroleum refining, for up to 10 hours in a temperature region between 200.degree. and 380.degree. C. and at a pressure of maximum 15 bar, with good inter-mixing of the reaction components, and thereafter separating the products by distillation from the pitch-like residue.
