<p>A process for converting coals or peat to principally hydrocarbon gases, by intimately contacting them with a reagent, e.g., alkali metalsulfide, polysulfide or hydrosulfide, in the presence of water steam, or a combination of steam and hydrogen, at temperatures between 65 DEG C to 450 DEG 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. <IMAGE></p> |
