Abstract
Resin-asphaltene substances (RAS) are the most representative group of non-hydrocarbon petroleum components, which have a negative effect on catalytic processes of oil refining and on the operational indices of petroleum products. At the same time they are one of the main reserves for further increasing the extent petroleum exploitation. Therefore, an understanding of the composition and structure of resin-asphaltene substances is of considerable importance both for oil refining and the production of high-grade petroleum products. Reasonably reliable information concerning the structural-group composition of resin-asphaltene substances has only been forthcoming in recent years as a result of the development of NMR spectroscopy and high-resolution mass-spectrometry. In this study structural-group composition of petroleum resins of the Fedorov deposit (Tyumen region), was obtained using mass-spectrometry, PMR- and /sup 13/C-NMR spectroscopy, elemental analysis and molar masses. 9 references, 3 tables.
