Abstract:
1. An integrated hydrocracking process for producing cracked hydrocarbons from a feedstock including: a. separating the hydrocarbon feed into an aromatic-lean fraction and an aromatic-rich fraction; b. hydroprocessing the aromatic-rich fraction in a first stage hydroprocessing reaction zone to produce a first stage hydroprocessing reaction zone effluent; c. fractionating the first stage hydroprocessing reaction zone effluent to produce one or more fractionating zone product streams and one or more fractionating zone bottoms streams; d. hydroprocessing a mixture of at least a portion of fractionating zone bottoms stream and aromatic-lean fraction in a second stage hydroprocessing reaction zone to produce a second stage hydroprocessing reaction zone effluent; and e. conveying the second stage hydroprocessing reaction zone effluent to the step of fractionating.
