1. A method of hydroprocessing heavy oil, comprising:
adding a first quantity of catalyst precursor to heavy oil and heating the heavy oil to form first dispersed metal sulfide catalyst particles in situ within the heavy oil;
hydroprocessing the heavy oil containing the first dispersed metal sulfide catalyst particles at hydroprocessing conditions to yield upgraded heavy oil containing converted products;
subjecting at least a portion of the upgraded heavy oil to solvent deasphalting to produce deasphalted oil and pitch, wherein at least a portion the first dispersed metal sulfide catalyst particles remain in the pitch after solvent deasphalting;
adding a second quantity of catalyst precursor to the deasphalted oil and heating the deasphalted oil to form second dispersed metal sulfide catalyst particles in situ within the deasphalted oil; and
hydroprocessing the deasphalted oil containing the second dispersed metal sulfide catalyst particles at hydroprocessing conditions to yield upgraded deasphalted oil containing converted products.
