Claim 0:
1. A method of hydroprocessing a hydrocarbon feed, the method comprising:
fractionating the 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; and
hydroprocessing the nth fraction and the (n−1)th effluent in an nth hydroprocessing reaction zone, thereby producing an nth effluent; wherein
the (n−1)th hydroprocessing reaction zone is upstream of the nth hydroprocessing reaction zone;
the (n−1)th fraction has a greater boiling point range than the nth fraction; and
hydrogen and the hydrocarbon feed are in co-current flow in the hydroprocessing unit.
