• Resumen

  • A complete physicochemicol charaterization of several crude oil fractions is occomplished and nuclear mognetic resonanceof 13C and 1H, column chromatogrophy, mass spectrometry and empiric correlations  are used to establish their chemical composition. The sensibility of these methodologies towards the chemicol composition chonges produced on some of these froctions by hydrotreolment is evaluated. The superiority of the mass spectrometry technique over the other analytical techniques for the characterization of lighter feeds is highlighted, its limitations are also shown for the analysis of the heavier ones that are better characterized by nuclear magnetic resonance and liquid chromatography.
