ABSTRACT:
A process for recovering hydrocarbons from coal or oil shale is disclosed. The process involves the steps of forming a pulp of finely divided coal or oil shale in a first reaction bed, adding concentrated sulphuric acid to the first reaction bed, controlling the temperature of the first reaction bed to produce a hydrocarbon mixture, and deacidifying the hydrocarbon mixture.
