ABSTRACT:
This invention relates to a process for upgrading a hydrocarbonaceous material having an initial boiling point of at least about 625.degree. F. to a product having a lower boiling point than the initial boiling point of said hydrocarbonaceous material and/or a higher boiling point than the final boiling point of said hydrocarbonaceous material, the process comprising heating a mixture comprising said hydrocarbonaceous material and at least one organic solvent in an enclosed space in the absence of externally supplied water or hydrogen at a temperature in the range of about 750.degree. F. to about 1300.degree. F. and a pressure in excess of about 1200 psig for an effective period of time to yield said product, said pressure being sufficient to maintain the specific gravity of the contents of said enclosed space in the range of about 0.05 to about 1.5, said organic solvent being capable of dissolving at least about 10 parts of said hydrocarbonaceous material per million parts of said organic solvent at the temperature wherein at least about 50% by weight of said organic solvent boils at atmospheric pressure.
