Abstract: A method for preparing a transportable fuel composition and for simultaneously producing electricity by utilizing a novel co-generation configuration. Coal or coal-derived fuels are used to generate electrical power. The waste heat from the power generation is used as the process heat for pyrolysis to produce a transportable, completely combustible slurry which contains particulate coal char and a liquid organic material.

Abstract: 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.

Abstract: Volatile, carbonaceous material is refined by hydrodisproportionation to produce a slate of co-products by heating the carbonaceous material 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.

Abstract: The rheology of a fluidic, substantially combustible non-polluting liquid/solid slurried fuel system derived in substantial part from hydrodisproportionation of coal is varied by addition of fluidic aqueous mixtures and lower chain alcohols to alter the rheology of the mixture and reduce the thermal NO.sub.x upon combustion.

Abstract: Coal char produced by the pyrolytic destructive thermal distillation of coal in the absence of oxygen is ground, sized and then admixed in suitable portions with water to form a fluidic, liquid-solid fuel system comprising a nonpolluting, stable, transportable, high energy fuel. The fuel system can be fired directly or the char can be separated and fired as a solid fuel. The liquid organic fraction obtained from the low boiling fractions derived from the pyrolysis of coal is used as a fuel or as a feed stock.

Abstract: Coal char produced by the pyrolytic destructive thermal distillation of coal in the absence of oxygen is ground, sized and then admixed in suitable portions with a liquid carbon dioxide to form a fluidic, liquid-solid mixture which is a transportation medium for a nonpolluting, stable, high energy solid fuel composition. The liquid organic fraction obtained from the low boiling fractions derived from the pyrolysis of coal is used as a feedstock or as a liquid hydrocarbon fuel.

Abstract: The rheology of a fluidic, combustible liquid/solid slurried fuel system derived in substantial part from the pyrolytic destructive thermal distillation of coal in the absence of oxygen and which is comprised of a pipeline transportable, nonpolluting fuel composition is varied by changing hydropyrolysis conditions to alter the viscosity of the liquid. Likewise, the viscosity of the liquid organic fraction which serves as the slurry medium or as a feedstock can be further varied by admixture with low boiling alcohols.

Abstract: Coal char, preferably produced by the pyrolytic destructive thermal distillation in the absence of oxygen of carbonaceous materials selected from lignites, peats, low rank coals, and waste coals, is beneficiated, ground and sized and then is admixed in suitable proportions with a liquid organic fraction to form a combustible, liquid/solid fuel system which is a nonpolluting, stable, transportable, high energy fuel compositions. The lower rank coals and peats are mechanically and/or thermally dehydrated prior to pyrolysis. Waste coals are beneficiated prior to pyrolysis. At least part of the liquid organic fraction is obtained from the pyrolysis of the carbonaceous material. Both the solid and the liquid portions can be used independently as fuel, or the solid/liquid fuel system can be fired directly.
