Abstract:
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; fractionating at least a portion of the hydrocracking effluent stream to provide a diesel stream; hydrotreating the diesel stream in the presence of a hydrotreating hydrogen stream and hydrotreating catalyst to provide a hydrotreating effluent stream; separating the hydrocracking effluent stream into a vaporous hydrocracking effluent stream comprising hydrogen and a liquid hydrocracking effluent stream; compressing the vaporous hydrocracking effluent stream with a compressed make-up hydrogen stream to provide a compressed hydrogen stream; and taking the hydrotreating hydrogen stream from the compressed hydrogen stream.
