Abstract
Coal can be extracted with high boiling aromatic oils produced by extracting the aromatic constituents of a heavy petroleum material, e.g. a bitumen residue, using a selective solvent, mixing the extract with a low-boiling aromatic solvent, adding water and separating the aromatic-containing phase and recovering said aromatic constituents. The resulting coal extract is particularly suitable for the production of electrode coke.
