Claim Text:
1. A process for producing diesel from a hydrocarbon stream comprising: hydrotreating a primary hydrocarbon stream and a co-feed hydrocarbon stream comprising diesel in the presence of a hydrogen stream and pretreating catalyst to provide a pretreated effluent stream; hydrocracking the pretreated effluent stream in the presence of hydrocracking catalyst and hydrogen to provide a hydrocracking effluent stream; separating the hydrocracking effluent in a separator to provide at least a vaporous hydrocracking effluent stream and a liquid hydrocracking effluent stream; fractionating at least the liquid hydrocracking effluent stream in a fractionation column to provide a diesel stream; and hydrotreating the diesel stream in the presence of a hydrotreating hydrogen stream and hydrotreating catalyst to provide a hydrotreating effluent stream.
