Oils of Kapaz deposit with hydrocarbon composition
B. A. GuseynovaThe results of the research of oils of Kapaz deposit with hydrocarbon (HC) composition are presented. The researches have shown that petroleum of Kapaz deposit is little-sulphured, resinous with few contents of asphaltenes, high contents of solid paraffin as earlier explored sea petroleum of light oil deposits. It is like the petroleum of Lam on its characteristic. Extraction of bright fraction of oil occurs at 200 C - 15 %, 300 C - 38 % mass. 50 degree oil fractions of Kapaz were divided into saturated and aromatic parts by liquid chromatography using the silica gel by the mark KCM and eluents. Structured - group and homology composition obtained from HC concentrate has been studied by the method of mass - spectrometry. Carried out researches have shown that the distillated parts of HC (150350 C) are presented basically in paraffin (18.7 %), mono- (6.5 % mass.) and bicyclical naphtene HC ( 4.7 % mass.). Alkylbensols and naphthalenes dominate among aromatic HC. It has been revealed that paraffin and aromatic HC in distillated parts (150350 C) of Kapaz oils is more than in oils of Lam. Isoparaffin and naphtene HC in specified petroleum exceed normal and aromatic paraffin. They are good raw materials to obtain high-quality fuels and oils.
