Claim One:
1. A method to control an xBOB output stream, which comprises: (a) spectroscopically analyzing an xBOB stream to produce spectrum of said analyzed xBOB product; (b) correcting said spectrum mathematically to produce a corrected spectra; (c) applying a calibration model to said corrected spectra; (d) obtaining predicted laboratory results from said calibration model; (e) transferring said predicted laboratory results to a control system; (f) modifying the ratio of blendstock components of said xBOB stream based on said results to produce an xBOB output stream that when said xBOB stream is combined with a fixed, known quantity of a predetermined oxygenate will produce an oxygenate-containing gasoline product having preset physical properties.
