Claim 1:
2. The method of claim 1, wherein “n” is at least 3; the method further comprising
hydroprocessing an (n−2)th fraction of the hydrocarbon feed in an (n−2)th hydroprocessing reaction zone of a hydroprocessing unit, thereby producing an (n−2)th effluent; wherein:
hydroprocessing the (n−1)th fraction of the hydrocarbon feed occurs in conjunction with the (n−2)th effluent, thereby producing the (n−1)th effluent;
the (n−2)th hydroprocessing reaction zone is upstream of the (n−1)th hydroprocessing reaction zone; and
the (n−2)th fraction has a greater boiling point range than the (n−1)th fraction.
