Application of Multidimensional Analysis Methods to Dead Oil Characterization on the Basis of Data on Thermal Field-Flow Fractionation of Native Asphaltene Nanoparticles

Molecular-mass distribution curves of native nanoasphaltenes in the form of fractograms for a significant sample of crude oils have been obtained using the thermal field-flow fractionation of asphaltenes, and a multidimensional analysis of the fractionation data has been carried out in order to construct calibration models for predicting the physicochemical properties of the studied oils.
