Combination slurry hydroconversion plus solvent deasphalting process for heavy oil upgrading wherein slurry catalyst is derived from solvent deasphalted rock

摘要

The invention described herein is directed to (a) slurry hydroprocessing (SHP) of a feed under SHP conditions; (b) deasphalting, under deasphalting conditions the product obtained from said step (a) and recovering a solvent deasphalted oil and solvent deasphalted rock; (c) calcining said solvent deasphalted rock at a temperature of ≦about 1200° F. to produce an ash catalyst precursor; (d) recycling said ash catalyst precursor to said step (a).
