ABSTRACT:
A process for recovering thermal values and organic materials from solid carbonaceous fuels, i.e., bituminous coals and lignites, by contacting such fuels with waste foul condensates, known as black liquor, from pulping operations thereby to solubilize thermal value containing organic materials therefrom and simultaneously provide a use for the heretofore considered unusable black liquors, the disposal of which up to now has presented both an economical and ecological problem.
