Claim:
1. An integrated hydrocracking process for producing cracked hydrocarbons from a feedstock including: a. separating, in an aromatic extraction zone, the hydrocarbon feed into an aromatic-lean fraction and an aromatic-rich fraction; b. hydroprocessing the aromatic-rich fraction in a first vessel of a first stage hydroprocessing reaction zone at a reaction pressure in the range from about 130 bar to 200 bar to produce a first vessel first stage hydroprocessing reaction zone effluent; c. hydroprocessing the aromatic-lean fraction in a second vessel of the first stage hydroprocessing reaction zone at a reaction pressure in the range from about 30 bar to 130 bar to produce a second vessel first stage hydroprocessing reaction zone effluent; d. hydroprocessing a mixture of first vessel first stage hydroprocessing reaction zone effluent and second vessel first stage hydroprocessing reaction zone effluent in a second stage hydroprocessing reaction zone to produce a second stage hydroprocessing reaction zone effluent; and e. fractionating the second stage hydroprocessing reaction zone effluent to produce one or more product streams and one or more bottoms streams.
