Claim 19:
20. The method of claim 1, wherein:
the hydrocarbon feed is a whole crude oil;
the residue stream is hydrotreated in a three stage hydrotreater;
the light stream and the hydrotreated residue stream have a greater residence time in the single FCC reaction zone than the middle stream;
the light stream and the hydrotreated residue stream are exposed to a peak temperature at least 10° C. greater than the middle stream, in the single FCC reaction zone;
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 540° 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 540° C.;
the residue stream comprises at least 99 wt. % of hydrocarbons boiling at greater than 540° C., based on the total weight of hydrocarbons in the residue stream; and
the residue stream comprises at least 99 wt. % of the hydrocarbons initially in the hydrocarbon feed which boil at greater than 540° C.
