Abstract:
1. A process to produce low sulfur diesel and a fluid catalytic cracker (FCC) quality feedstock, the process comprising: (a) reacting a hydrocarbonaceous feedstock in a hydrotreating zone containing a hydrotreating catalyst at conditions effective to produce a hydrotreating zone effluent having a reduced concentration of sulfur and nitrogen; (b) separating the hydrotreating zone effluent in a fractionating zone into at least a diesel boiling range hydrocarbon stream and the FCC quality feedstock; (c) selecting at least a first portion and a second portion of the FCC quality feedstock and combining the first portion with the diesel boiling range hydrocarbon stream to form a hydrocracking zone feed stream; (d) reacting the hydrocracking zone feed stream in a hydrocracking zone having at least a hydrocracking catalyst at conditions effective to produce a hydrocracking zone effluent including the low sulfur diesel having less than about 10 ppm sulfur; (e) passing the hydrocracking zone effluent into the fractionating zone to separate the low sulfur diesel; and (f) directing the second portion of the FCC quality feedstock to a fluid catalytic cracking unit.
