Low rank coals, waste coals and peat are refined by hydrodisproportionation to produce a slate of co-products by heating these materials in the presence of hydrogen donor rich reducing atmosphere and quenching the reaction vapor produced. The slate of co-products includes a fluidic, combustible non-polluting liquid/solid transportable fuel system derived in substantial part from said hydrodisproportionation.

An improved method for refining a carbonaceous material selected from low rank coals, waste coals, peat, or mixtures thereof, to produce a slate of hydrocarbon containing co-products by short residence time hydrodisproportionation comprising the steps of: (a) contacting said carbonaceous material at a volatilization temperature for a time sufficient to volatilize said carbonaceous material, with a hydrogen donor rich gaseous reducing atmosphere which is obtained in substantial part from said carbonaceous material wherein said hydrogen donor rich gaseous atmosphere and said volatilizing temperatures are produced in substantial part in a partial oxidation reaction wherein steam and hydrodisproportionation recycle gas rich in methane and carbon monoxide are reacted with a sub-stoichiometric amount of oxygen, to yield char and hydrocarbon containing vapor; and (b) cooling said vapor to reduce the temperature of said vapor below said volatilization temperature.
