Claim 19:
20. 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 200° 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 200° C.;
the middle stream comprises at least 99 wt. % of hydrocarbons boiling at from 200° C. to 370° C., based on the total weight of hydrocarbons in the middle stream;
the middle stream comprises at least 99 wt. % of all hydrocarbons initially in the hydrocarbon feed which boil at from 200° C. to 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;
a peak temperature in the first FCC reaction zone is at least 20 degrees Celsius greater than a peak temperature in the third FCC reaction zone; and
a peak temperature in the second FCC reaction zone is at least 20 degrees Celsius greater than a peak temperature in the third FCC reaction zone.
