ABSTRACT:
Sulfur compounds are removed from coal during preparation of the coal for pipeline transport and during pipeline transport of the coal by preparing the coal in particles sufficiently fine for transport as an aqueous slurry, mixing the coal particles with oxygenated water and a basic chemical substance, transporting the coal as a slurry in a pipeline, separating the coal from water containing soluble sulfur compounds and from sludge-containing insoluble sulfur compounds.
