Claim:
1. A method for processing a heavy oil feedstock, comprising: providing a combined feedstock comprising a heavy oil feedstock having a 10% distillation point of at least about 650° F. (343° C.) and a solvent component, wherein the solvent component has an ASTM D86 90% distillation point of less than 300° C.; exposing the combined feedstock to a catalyst in the presence of hydrogen under first effective hydroprocessing conditions to form a first slurry hydroconversion effluent comprising at least a first plurality of liquid products and a first hydroprocessing bottoms product, the first effective hydroprocessing conditions including a temperature of at least about 680° F. (360° C.) and a liquid hourly space velocity of the fraction of the combined feedstock boiling above 1050° F. (566° C.) of at least about 0.10 hr exposing the first hydroprocessing bottoms product to a catalyst in the presence of hydrogen under second effective slurry hydroconversion conditions to form a second slurry hydroconversion effluent comprising at least a second plurality of liquid products and a second hydroprocessing bottoms product; and fractionating the first plurality of liquid products and the second plurality of liquid products.
