Claim 5:
6. The method of claim 1, wherein:
the FCC processing unit comprises:
a reactor positioned to receive the hydrocarbon feed and a catalyst, thereby to promote catalytic cracking of the hydrocarbon feed into the FCC effluent, the hydrocarbon feed and the catalyst providing a reaction mixture, and
a riser associated with the reactor, and

the method further comprises:
analyzing, via a spectroscopic analyzer, a reaction mixture sample at an outlet of the riser, and
analyzing, via the second spectroscopic analyzer, the FCC effluent at an outlet of the reactor, wherein the analyzing the reaction mixture sample at the outlet of the riser and the analyzing the FCC effluent at the outlet of the reactor occur substantially during a concurrent time period, and
wherein analyzing the reaction mixture comprises analyzing the reaction mixture via one of the first spectroscopic analyzer, the second spectroscopic analyzer, or a third spectroscopic analyzer.
