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.

A combustible, fluidic, substantially non-polluting fuel system comprising a liquid/solid mixture, including a portion of a solid particulate coal char obtained by pyrolysis of lignites, peats, low rank coals, waste coals and mixtures thereof, dispersed in an amount of a liquid material effective to produce a transportable composition, wherein said liquid material is at least partially derived from said pyrolysis; or is a mixture of said pyrolysis material with a lower chain alcohol of from 1 to 4 carbon atoms.
