The thermal hydrogenation of solid coal without added catalyst produces hydrocarbon gases in the methane to propane range as the principal product, plus substantial yields of synthetic petroleum-like hydrocarbon liquids. The C4-400 DEG F. naphtha liquid fraction is steam reformed to produce hydrogen, while heavier distillate liquid fractions are used as fuel to operate the steam reformer and for other process heat requirements, so that all of the hydrogen required for the coal hydrogenation reaction is produced from portions of the liquid products.
