Adsorptive Separation and Study of Narrow Oil Fractions (bp 300-400°C) of West Surgut Oil

Аннотация

Increased production and processing of sulfur crudes has necessitated a comprehensive study of their compositions and properties because of the development of modern desulfurization technologies for oil fractions and the use of organosulfur compounds as new feedstocks for the petrochemical industry. Adsorptive separation of oil distillate into narrow fractions over ShSM silica gel was used to study the composition and properties of the organosulfur compounds. IR and mass spectroscopy found that organosulfur compounds from West Surgut oil fractions were aliphatic and cyclic sulfides without aromatic sulfides and thiophenes (alkyl-, cycloalkano-, bicycloalkanobenzothiophenes).
