    摘要: The present invention concerns a prediction method of chemical-physical properties of a fraction of atmospheric and/or vacuum distillation of a oil, which comprises the following steps:
    - withdrawing a first sample of said oil and obtaining its 1 H NMR spectrum;
    - withdrawing a second sample of said oil and analytically determining, according to standard analytical methods, the same physical properties for which it is desired to make a prediction with respect to said fraction of atmospheric and/or vacuum distillation or subjecting it to atmospheric distillation and withdrawing a sample of a residue of said atmospheric distillation and determining according to the prediction method, the same physical properties of which it is desired to obtain the prediction with respect to said fraction of vacuum distillation;
    - building a "expanded spectrum" by concatenating the 1 H NMR spectrum of said first sample of said oil with the chemical and physical properties determined on said second sample of said oil or on said sample of the residue of said atmospheric distillation;
    - obtaining the desired property of said distillation fraction inputting the data obtained from the preceding steps in a mathematical expression, representative of the prediction model, previously obtained by:
    I. selecting a set of oils representative of those on which the analysis will have to be carried out;
    II. obtaining the spectra of said oils through the 1 H NMR technique;
    III. preparing atmospheric and/or vacuum residues by distillation of said oils;
    IV. determining a set of chemical-physical properties of said oils by means of standard analytical methods;
    V. determining a set of chemical-physical properties of said atmospheric and/or vacuum residues by means of standard analytical methods;
    and subsequent building and calibrating of the prediction model through the following steps
    VI. producing a set of "expanded spectra", obtained by the concatenation of the data of chemical-physical properties of step IV, in the case of determination of physical properties of a fraction of atmospheric distillation, or of the atmospheric residues of step V, in the case of determination of physical properties of a fraction of vacuum distillation, with the spectra obtained in step II;
    VII. making a regression, with a method of multivariate calibration, of the set of "expanded spectra" obtained in step VI with the chemical-physical properties of the atmospheric residues of step V, in the case of determination of physical properties of a fraction of atmospheric distillation, or with the chemical-physical properties of atmospheric and/or vacuum residues of step V, in the case of determination of physical properties of a fraction of vacuum distillation.
