Claim 4:
5. 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,
the method further comprises analyzing, via one or more spectroscopic analyzers, a reaction mixture sample taken from one or more locations of the reactor, the one or more spectroscopic analyzers calibrated so as to generate standardized spectral responses, and
one or more of:
(i) analyzing the reaction mixture sample taken from the one or more locations of the reactor comprises analyzing the reaction mixture sample taken from the one or more locations of the reactor via respective spectroscopic analyzers, the respective spectroscopic analyzers being calibrated so as to generate standardized spectral responses,
(ii) the FCC processing unit comprises a riser associated with the reactor, and the method further comprising analyzing, via one of more spectroscopic analyzers, two or more reaction mixture samples taken from two or more different points along a height of the riser, the one or more spectroscopic analyzers calibrated so as to generate standardized spectral responses, or
(iii) the FCC processing unit comprises a riser associated with the reactor, and the method further comprising analyzing, via the second spectroscopic analyzer, a reaction mixture sample at an outlet of the riser.
