Process for upgrading hydrocarbonaceous materials.

摘要

This invention relates to a process for upgrading a hydrocarbonaceous material 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 feed composition comprising said hydrocarbonaceous material in an enclosed space in the absence of externally supplied water or hydrogen at a temperature in the range of about 750 DEG F to about 1300 DEG F and a pressure sufficient to maintain the specific gravity of the contents of said enclosed space in the range of about 0.05 to about 1.5 for an effective period of time to yield said product, said feed composition being characterised by the absence of aromatic compounds with boiling points at atmospheric pressure below about 350 DEG F.
