Aromatic hydrocarbons are obtained by reforming a gasoline employing the hydrogen formed to hydrorefine a coke oven light oil derived from coal and containing non-hydrocarbon impurities, combining the refined oil and the reformate and solvent extracting to obtain an aromatic fraction. The reforming may be effected with a platinum or palladium catalyst supported on alumina with or without halogen, silica-alumina or silica magnesia at 425-600 DEG C. and 3-70 atmospheres with a hydrogen to hydrocarbon mol. ratio between 1 and 15:1. The gasoline may be a full boiling range straight-run gasoline or have an initial boiling point between 65-120 DEG C. and a final boiling point of 145-190 DEG C. The volume ratio of gasoline to coke oven light oil is generally 0.25 to 0.4:1. The hydrofining may be effected with a mixture of the oxides or sulphides of cobalt and molybdenum supported on alumina, silicaalumina, silica-magnesia or magnesia-alumina or composites of nickel and tungsten sulphides supported on alumina or silica-alumina, at 315-425 DEG C. and 3-100 atmospheres. Either or both of the liquid products from the two stages may be fractionated to separate materials boiling below and/or above the desired hydrocarbon, e.g. a benzene cut, a toluene cut, a xylene cut, a benzene-toluene cut or a toluenexylene cut may be separated. The solvent extraction may be effected with a glycol, e.g. ethylene, diethylene, propylene, dipropylene, butylene or dibutylene glycol or mixtures thereof, together with, if desired, 2-25% (by weight of the total solvent) of water. Alcohols, phenols, ethers, nitriles or esters can also be used. A temperature of atmospheric to 250 DEG C. can be used at 2-25 atmospheres to maintain the liquid phase using 2-20 volumes of solvent per volume of hydrocarbon. The raffinate may be recycled to the reforming operation. Aromatic hydrocarbons are stripped from the solvent and fractionated to separate individual hydrocarbons if desired and may be purified by contact with clay or other adsorbent at up to 250 DEG C.ALSO:Aromatic hydrocarbons are obtained by reforming a gasoline employing the hydrogen formed to hydrorefine a coke-oven light oil derived from coal and containing non-hydrocarbon impurities, combining the refined oil and the reformate and solvent extracting to obtain an aromatic fraction.
