ABSTRACT:
This invention relates to a novel integrated hydroconversion process for converting heavy atmospheric or vacuum residue feeds and also converting and reducing impurities in the vacuum gas oil liquid product. This is accomplished by utilizing two residue hydroconversion reaction stages, two vapor-liquid separators, and at least two additional distillate ebullated-bed hydrocracking/hydrotreating reaction stages to provide a high conversion rate of the residue feedstocks.
