ABSTRACT:
A process for recovering and upgrading products from solid coal by contacting the coal with a dense-water-containing fluid at a temperature in the range of from about 600.degree.F. to about 900.degree.F. in the absence of externally supplied hydrogen or other reducing gas and in the presence of a sulfur- and nitrogen-resistant catalyst. The density of water in the water-containing fluid is at least 0.10 grams per milliliter, and sufficient water is present to serve as an effective solvent for the recovered liquids and gases.
