Pulverized coal is slurried with hydrogen donor solvent at atmospheric pressure and fed directly into a coker furnace and coking drum. Overhead products from the coking drum are fractionated, and a portion thereof is hydrogenated and used as donor solvent. Coke is calcined in a vertical shaft calciner, and calcined coke is contacted with steam in the calciner to produce hydrogen. The hydrogen is used to hydrogenate the donor solvent.
