Abstract

Some organic sulfur compounds (OSCs) in crude oil may be derived from thermochemical interactions between petroleum and sulfates in deep buried sedimentary basins. In the present study, experiments on the system of 2, 2, 4-trimethylpentane–MgSO4–H2O were operated at elevated temperatures and elevated pressures. Properties of the products were characterized and the reaction kinetics was tentatively investigated. The results demonstrated that the oxidation of 2, 2, 4-trimethylpentane by MgSO4 occurs above 425 ℃ to produce a series of organic sulfur compounds, including mercaptans, sulfoethers and thiophenes. The calculated activation energy of the reaction between 2, 2, 4-trimethylpentane and MgSO4 is 50.236 kJ/mol.
