ABSTRACT 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°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 require- ments, so that all of the hydrogen required for the coal hydrogenation reaction is produced from portions of the liquid products.
