Distribution of high-molecular-weight n-alkanes in paraffinic crude oils and asphaltene-resin-paraffin deposits

Ganeeva, Yu. M. / Foss, T. R. / Yusupova, T. N. / Romanov, A. G.

Abstract Paraffinic and high-paraffin oils and asphaltene-resin-paraffin (ARP) deposits of Samara oblast have been investigated by differential scanning calorimetry (DSC) and GLC techniques. High-paraffin oils have been found to contain n-alkanes with the number of carbon atoms of C15-C60 and higher forming a crystalline phase with the mp ∼30–40°C. The ARP deposits from high-paraffin oils almost do not contain highmolecular-weight n-alkanes with the number of carbon atoms >55. This is due to the peculiarities of the crystallization and cocrystallization processes of high polydispersity n-alkanes in crude oils.
