Abstract: A process for maximizing production of heavy naphtha from a hydrocarbon stream is disclosed. The process comprises providing a hydrocarbon feed stream comprising diesel to a separation column to provide a light diesel stream and a heavy diesel stream. The heavy diesel stream is hydrocracked in the presence of a hydrogen stream and a first hydrocracking catalyst in a first hydrocracking reactor at a first hydrocracking pressure of 13790 kPa to 17237 kPa to provide a first hydrocracked effluent stream. The light diesel stream is hydrocracked in the presence of a hydrogen stream and a second hydrocracking catalyst in a second hydrocracking reactor at a second hydrocracking pressure of 3450 kPa to 6205 kPa to provide a second hydrocracked effluent stream. At least a portion of the first hydrocracked effluent stream and at least a portion of the second hydrocracked effluent stream are fractioned to produce heavy naphtha.
