Observations about the Structure and Dispersion of Petroleum Asphaltenes Aggregates Obtained from Dialysis Fractionation and Characterization
A sample of asphaltenes (ACN) precipitated from Cerro Negro crude oil had been divided into 14 fractions using a dialysis procedure employing THF-acetone mixtures as the extracting solvent. Seven extracts (F1-F7) and the corresponding residues R1-R7 were obtained as the mixture composition changed f...
