Resumo: | |||||||||||||||||||||||||||||||||||||||||
The determination of the gasoline components, and the
contribution of these in the
quality and final performance, had in the past a great
number of studies that can create
routines for the monitoramento of this fuel. The objective
of this work is to identify and to
quantify the main groups of composites that compose the
distributed commercial gasoline
in part of the Southeastern region, through multivaried
analysis of data of FT-Raman
spectroscopy, through regression for Squared Minimums
Partial (PLS - Partial Least
Squares) using for the analysis of the main components
(PCA), 120 random samples of
the fuel laboratory of PUC-Rio in the period of January the
June of 2004, which is part of
the program of fuel control. All the samples had been
submitted to the analysis for
gaseous chromatography (GC) and FT-Raman spectroscopy in
the same day. The FTRaman
spectra had been all collected, and had been determined the
concentration of the
main component groups of the composition of the commercial
gasolinas for method
PONA/PEONA for paraffin(P), olefin(O), naphthene(N),
aromatic(A) and ethanol(E). The
experimental data had been treated by PLS/PCA in order to
get a correlation of each
specific region of the FT-Raman spectra with the results
giving for GC through methods
PONA/PEONA.
