Patent ID: 11965135

Abstract:
A method of hydroprocessing a hydrocarbon feed may comprise fractionating a hydrocarbon feed into “n” fractions, wherein “n” is at least 2; hydroprocessing an (n−1)th fraction of the hydrocarbon feed in an (n−1)th hydroprocessing reaction zone of a hydroprocessing unit, thereby producing an (n−1)th effluent The method may further comprise hydroprocessing the nth fraction and the (n−1)th effluent in an nth hydroprocessing reaction zone, thereby producing an nth effluent. The (n−1)th hydroprocessing reaction zone may be upstream of the nth hydroprocessing reaction zone. The (n−1)th fraction may have a greater boiling point range than the nth fraction. Hydrogen and the hydrocarbon feed may be in co-current flow in the hydroprocessing unit.
