Each of such products is delayed coked in separate zones with the vapors from such zones being introduced into a common combination coker-fractionator to recover ash containing and ash free coking recycle, pasting solvent for the liquefaction and lighter products. The process is particulary applicable to coal liquefaction products produced from high ash containing coals.
