ABSTRACT:
This invention provides a process for upgrading heavy hydrocarbon oil by thermal treatment which in one preferred embodiment involves heating a petroleum residuum type of heavy oil feedstock at a temperature of 450.degree.-550.degree. C. and a pressure of 10-200 psi for a period of about 0.1-1 hour to convert at least 60 weight percent of the heavy oil to gasoline and gas oil range products, and additionally providing a residual tar fraction which has a fusion temperature below about 160.degree. C.
About 1-10 weight percent of solid carbonaceous fines are incorporated in the feedstock to suppress the deposition of coke in the thermal treatment zone.
