ABSTRACT OF THE DISCLOSURE Disclosed is a method for enhancing the con- version of carbonous materials, such as coal and oil shale. The method comprises converting the carbonous material in the presence of a vapor phase hydrogen donor material containing one or more hydrogen donor solvents wherein each donor material is characterized by: (a) a heterocyclic ring in which the heteroatom is nitrogen, (b) having at least one donatable hydrogen located on the heterocyclic ring, and (c) becoming more unsaturated and/or aromatic upon the loss of the donata- ble hydrogen(s). The conversion is performed at sub- stantially atmospheric pressure, at an effective vapor residence time and at a temperature from about the boil- ing point of the hydrogen donor material to about 550°C.
