ABSTRACT:
Coal is processed sequentially over a range of temperatures up to a maximum of 750.degree. F. and preferably considerably less to obtain a clean burning coke, refinable petroleum and bitumen products, fertilizer minerals, combustible gases and water; the process is capable of producing a highly porous, easily crushed coke substantially free of pollutants and almost entirely depleted of oil so that it is hygroscopic and easily transformed to a pipeline slurry. The process is not one of destructive distillation but neither is atmospheric air employed as a combustion oxidant or reactant in the system; the process is preferably conducted under reflux conditions in a closed vessel and in such a way that the heat input is complemental substantially to the thermo-absorption spectrum of the coal.
