Abstract
In an ebullated bed process, a nominal 1000.degree. F.+ boiling point vacuum residuum is hydrotreated at a first temperature of 750.degree. F. to 875.degree. F. and total pressure of 1900 psig to 3000 psig. Hydrogen partial pressure is controlled by changing total reactor pressure in the range of 1700 psig to 2300 psig to achieve a selected yield of 650.degree. F.- boiling material.
