Fuel suitable for diesel motors is made by hydrogenating carbonaceous materials such as coal, lignite, coal extracts, and primary bitumen to produce oils poor in H and adding oils rich in H.  The oils rich in H may be obtained by synthesis from CO and H₂ or by hydrogenating carbonaceous materials.  Solid bituminous hydrocarbons, such as coal extracts and primary bitumens obtained from coal, may also be added.
