Claim 17:
18. The method of claim 1, wherein:
the hydrocarbon feed is a whole crude oil;
the heavy stream is hydrotreated in a three stage hydrotreater;
the light stream has a greater residence time in the single FCC reaction zone than the middle stream;
the light stream is exposed to a greater peak temperature in the single FCC reaction zone than the middle stream;
the middle stream has a greater residence time in the single FCC reaction zone than the hydrotreated heavy stream;
the middle stream is exposed to a greater peak temperature in the single FCC reaction zone than the hydrotreated heavy stream;
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 the hydrocarbons initially in the hydrocarbon feed which boil at a temperature of less than 200° C.;
the middle stream comprises at least 99 wt. % of hydrocarbons boiling from 200° C. to 371° C., based on the total weight of hydrocarbons in the middle stream;
the middle stream comprises at least 99 wt. % of the hydrocarbons initially in the hydrocarbon feed which boil at a temperature from 200° C. to 371° C.;
the heavy stream comprises at least 99 wt. % of hydrocarbons boiling at greater than 371° C., based on the total weight of hydrocarbons in the heavy stream; and
the heavy stream comprises at least 99 wt. % of the hydrocarbons initially in the hydrocarbon feed which boil at greater than 371° C.
