Sažetak
The characterization of crude oils and their heavy fractions is an important task in oil industry with regard to quality of final products. A common characteristic of oil samples is a complex chemical composition. Components present in oil samples differ in structure, size, polarity and functionality. One of the main problems during oil recovery and refining process is associated with the presence of the compounds called asphaltenes. In this work NMR spectroscopy in combination with automated flocculation titration method was used to study three different crude oils and their fractions, vacuum gas oils and residues. Pseudo two‐dimensional DOSY NMR technique was applied to separate components from crude oils according to their diffusion coefficients. Furthermore, asphaltenes were isolated from crude oil and their fractions. Asphaltenes are complex organic macromolecular mixtures containing condensed aromatic and saturated rings, aliphatic moieties and different heteroatoms. They can cause many problems during production, such as blocking of production pipes, reduction in oil flow and catalyst deactivation. Despite many efforts and a variety of analytical methods used, the complex asphaltene structures are not completely elucidated.
