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 371° C., based on the total weight of the light stream;
the light stream comprises at least 99 wt. % of all hydrocarbons initially in the hydrocarbon feed which boil at less than 371° C.;
the heavy stream comprises at least 99 wt. % of hydrocarbons boiling at greater than 371° C., based on the total weight of the heavy stream;
the heavy stream comprises at least 99 wt. % of all hydrocarbons initially in the hydrocarbon feed which boil at greater than 371° C.;
the light stream has a residence time in the FCC at least 1 second greater than the hydrotreated heavy stream;
the light stream is exposed to a peak temperature in the reaction zone at least 25° C. greater than the hydrotreated heavy stream; and
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.
