Based on the existing problems in characterization of petroleum fractions with pseudo-components and real-components methods,a new real-components method was proposed,by which the fractions in narrow distillation ranges were characterized with some real-components contained structrure informations according to the properties of the fractions in different distillation ranges.

New and reliable empirical correlations for predicting the average boiling points of petroleum fractions,which include mass average boiling point, molar average boiling point, cubic average boiling point and mid-average boiling point,were proposed and the deviation was analyzed.

Structural parameters, such as 1 H NMR spectrum, hydrogen and carbon atom contents,for 20 petroleum fractions from two crude oils were determined by using nuclear magnetic resonance (NMR) spectroscopy and elemental analysis.
