Claim 18:
19. The method of claim 1, wherein:
the hydrocarbon feed is a whole crude oil;
the light stream comprises at least 99 wt. % of hydrocarbons boiling at less than 370° C., based on the total weight of hydrocarbons in the light stream;
the light stream comprises at least 99 wt. % of all hydrocarbons initially in the hydrocarbon feed which boil at less than 370° C.;
the heavy stream comprises at least 99 wt. % of hydrocarbons boiling at greater than 370° C., based on the total weight of hydrocarbons in the heavy stream;
the heavy stream comprises at least 99 wt. % of all hydrocarbons initially in the hydrocarbon feed which boil at greater than 370° C.;
hydrotreating the heavy stream comprises contacting the heavy stream with a hydro-demetallization catalyst, a hydro-desulfurization catalyst, and a hydro-dearomatization catalyst in the presence of hydrogen;
the first and second FCC reaction zones are operated under high severity conditions; and first FCC reaction zone is operated at a temperature at least 20 degrees Celsius greater than the second FCC reaction zone.
