This patent describes an integrated coking and hydroconversion process which comprises the steps of: (a) treating a carbonaceous feed having a Conradson carbon content of at least 5 weight percent in a delayed coking or fluidized coking zone at coking conditions to produce coke and a vapor phase product having hydrocarbons boiling about 1050F, (b) separating a heavy bottoms fraction having the hydrocarbons boiling above 1050F from the vapor phase product; (c) adding asphalt, and an oil soluble metal compound hydrocarbon catalyst precursor or a thermally decomposable metal compound catalyst precursor to at least a portion of the heavy bottoms fraction to form a mixture comprised of from about 40 to 85 weight percent asphalt; and (d) subjecting the mixture of step (c) to hydroconversion conditions within the temperature range of about 650 to about 1000f and a hydrogen partial pressure of about 100 to 8,000 psig, in the presence of hydrogen, in a slurry hydroconversion zone to convert the mixture or portion of the mixture to lower boiling products.
