BALDRICH FERRER, Carlos-A.. PREDICTION OF PHYSICOCHEMICAL PROPERTIES OF FCC FEEDSTOCK BY CHEMOMETRIC ANALYSIS OF THEIR ULTRAVIOLET SPECTRUM. C.T.F Cienc. Tecnol. Futuro [online]. 2008, vol.3, n.4, pp.143-156. ISSN 0122-5383.

Chemometric analysis by Partial Least Squares (PLS) has been applied in this work to correlate the ultraviolet spectrum of combined Fluid Catalytic Cracking (FCC) feedstocks with their physicochemical properties. The prediction errors obtained in the validation process using refinery samples demonstrate the accuracy of the predicted properties. This new analytical methodology allows obtaining in one analysis detailed information about the most important physicochemical properties of FCC feedstocks and could be used as a valuable tool for operational analysis.

Palabras clave : fluid catalytic cracking; petroleum fraction; physicochemical property; chemometric; ultraviolet spectroscopy.
