Claim Text:
1. A process for producing diesel from a hydrocarbon stream comprising: feeding a hydrocarbon stream to a hydrotreating reactor; hydrotreating the hydrocarbon stream in the presence of a hydrogen stream and pretreating catalyst to provide a pretreated effluent stream; separating said pretreated effluent stream into a vaporous pretreated stream and a liquid pretreated stream; hydrocracking the liquid pretreated stream in the presence of hydrocracking catalyst and hydrogen to provide a hydrocracking effluent stream; mixing said vaporous pretreated stream with the entire hydrocracking effluent stream to provide a mixed hydrocracking effluent stream; fractionating at least a portion of the mixed hydrocracking effluent stream 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.
