Abstract
A hydrocracking process for maximization of naphtha while producing base oil is disclosed. The hydrocracking process comprises hydrocracking a hydrocarbon feed stream in a hydrocracking unit in the presence of a hydrogen stream and a hydrocracking catalyst to produce a hydrocracked effluent stream. The hydrocracked effluent stream is separated in a separator to provide a vapor hydrocracked stream and a liquid hydrocracked stream. The liquid hydrocracked stream is fractionated to provide a naphtha stream, a kerosene stream, a diesel stream and a first unconverted oil stream. A recycle stream comprising a portion of the kerosene stream, a portion of the diesel stream, and a portion of the first unconverted oil stream is recycled to the hydrocracking unit to provide a second unconverted oil stream. A remaining portion of the first unconverted oil stream is withdrawn for base oil production.
