Claim 16:
17. The process as in claim 15, further comprising: treating at least a portion of the vacuum residue to produce at least naphtha-range hydrocarbons as a fourth naphtha source, wherein treating is by hydrotreating followed by hydrocracking, hydrotreating followed by fluid catalytic cracking, or delayed coking; optionally subjecting naphtha from the fourth naphtha source to deep hydrodesulfurization and deep hydrodenitrogenation, and wherein catalytic reforming further comprises reforming all or a portion of the fourth naphtha source, optionally subjected to deep hydrodesulfurization and deep hydrodenitrogenation; and gasifying heavy products from treating vacuum residue including pitch wherein treating is by hydrotreating followed by hydrocracking, heavy cycle oil wherein treating is by hydrotreating followed by fluid catalytic cracking, or heavy coker gas oil and/or coke wherein treating is by delayed coking, or coke wherein treating is by delayed coking, wherein gasifying produces hydrogen that used during reaction of reformate in the presence of a hydrogenation catalyst to produce cyclohexanes.
