Claim 0:
1. A process for separating and upgrading a naphtha feed, the process comprising:
passing the naphtha feed to a naphtha separation unit that separates the naphtha feed into at least a light naphtha fraction and a heavy naphtha fraction;
passing the light naphtha fraction to a cyclization unit that contacts the light naphtha fraction with hydrogen in the presence of at least one cyclization catalyst to produce a cyclization effluent comprising a greater concentration of naphthenes compared to the light naphtha fraction, wherein the at least one cyclization catalyst comprises ultra-stable Y-type (USY) zeolite and platinum as an active phase metal supported on the USY zeolite, the cyclization catalyst comprises from 60 weight percent to 80 weight percent USY zeolite based on the total weight of the cyclization catalyst, and the cyclization unit operates at a temperature of 475° C., a hydrogen partial pressure of 0.3 MPa (3 bar), and a molar ratio of hydrogen to light naphtha fraction of 3; and
passing the cyclization effluent to a fluid catalytic cracking unit that contacts the cyclization effluent with at least one cracking catalyst at a temperature of from 650° C. to 700° C., a pressure of from 0.1 1VIPa to 1 1VIPa, and a weight ratio of the cracking catalyst to the cyclization effluent feed of from 1:2 to 1:30, where the contact of the cyclization effluent with the at least one cracking catalyst cracks at least a portion of the cyclization effluent to produce a fluid catalytic cracking effluent comprising light olefins, gasoline blending components, or both;
passing the heavy naphtha fraction to a naphtha reforming unit that contacts the heavy naphtha fraction with at least one reforming catalyst to undergo one or more reactions under conditions sufficient to produce a reformate effluent, wherein the at least one reforming catalyst consists of:
a precious metal selected from the group consisting of platinum,
palladium, and combinations thereof; and

a catalyst support selected from the group consisting of alumina, silica, titania, and combinations thereof.
