Abstract
The octane of components used in the blending of gasoline is used to predict the octane of the finished gasoline blend by measuring absorbances, preferably in the near-infrared range, and metering the fraction of each blending component as independent variables and performing a multiple regression on the data modeling the dependent variable of the various octanes. Percent aromatics in diesel fuel and other finished chemical or physical properties of the finished blend can be controlled by feed-forward and/or feed-back techniques.
