Abstract
An integrated upgrading process is disclosed which can be used to lower the specific gravity, viscosity and boiling range of heavy, viscous hydrocarbonaceous oil by means of fractionally distilling the oil, treating its residuum with a hydrogen donor material under hydrocracking conditions, fractionally distilling the effluent from the hydrocracking zone and rehydrogenating that portion boiling from about 180.degree. C. to 350.degree. C. for recycling to the hydrocracking zone. The liquid portion of the oil not recycled can be recombined into a reconstituted crude suitable for transporting by normal crude pipelines.
