Abstract

Recovering liquid and gaseous hydrocarbons from solid raw materials containing hydrocarbons such as oil shale or coal by treating with a solvent oil at a temperature of 610.degree. K.-690.degree. K. and under pressure in the presence of hydrogen. The oil solvent is introduced into a heated vessel in vapor form. The raw material is introduced into the heated reaction vessel at a temperature below the condensation temperature of the oil to cause the oil vapor to condense at the surface of the raw material. The reaction vessel is heated to cause the raw material leaving the reaction vessel to be at a temperature above the condensation temperature of the oil at the pressure prevailing in the reaction vessel.
