Abstract:
1. A process of producing hydrocarbons from a coal, lignite, or oil shale and the like carbon and sulfur containing materials including the steps of forming a pulp of finely divided carbon-containing material in a first reaction bed, adding concentrated mono sulphuric acid to said first reaction bed, to degrade the carbon and sulfur containing material in the first reaction bed to hydrocarbons and a solid residue, controlling the temperature of said first reaction bed to between 70° C. and 200° C. to produce a hydrocarbon mixture, and deacidifying said hydrocarbon mixture by the steps including combining finely divided iron and water with the hydrocarbon mixture, the metallic iron combining with the residual acid in the hydrocarbon mixture to form a neutralized liquid hydrocarbon mixture.
