Abstract
On-line controlling of catalytic cracking processing is provided which uses near infrared (NIR) analysis to characterize cracking feed for parameters such as saturates, aromatics, and thiophene content and the resulting characterization thereof. The NIR results can be used in FCC software to control on-line unit yields and qualities.
