ABSTRACT OF THE DISCLOSURE A process for converting coals to principally hydrocarbon gases, by intimately contacting coals such as lignite coal with a reagent, e.g., alkali metal polysulfides or alkali metal hydrosulfide, in the presence of steam, or a combination of steam and hydrogen, at temperatures between 65° to 450°C. Liquid and gaseous hydrocarbons of preselected compositions may be produced; as it is well known these are useful as fuel, or as chemical starting materials, e.g., for upgrading fuel or making industrial chemicals.
