  • Co-processing of light cycle oil and heavy naphtha
    Patent number: 11104855
    Abstract: Processes for co-processing a naphtha stream with a light cycle oil stream are disclosed. The processes include hydrocracking the light cycle oil stream under hydrocracking conditions to provide a hydrocracked effluent stream. A naphtha stream is hydrotreated under hydrotreating conditions to provide a hydrotreated effluent stream. The hydrocracked effluent stream and the hydrotreated effluent stream may be passed to a stripping column to recover a stripping bottom stream. The stripping bottom stream may be passed to a main fractionation column to recover an intermediate naphtha stream.
