Characterization of Heteroatom Compounds in a Crude Oil and Its Saturates, Aromatics, Resins, and Asphaltenes (SARA) and Non-basic Nitrogen Fractions Analyzed by Negative-Ion Electrospray Ionization Fourier Transform Ion Cyclotron Resonance Mass Spectrometry

Abstract: A Liaohe crude oil was separated as saturates, aromatics, resins, and asphaltenes (SARA) and neutral nitrogen fractions. The crude oil and its subfractions were analyzed by negative-ion electrospray ionization (ESI) Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS). The results show that neutral nitrogen and acidic heteroatom compounds in the crude oil contain 15-55 carbon atoms with double-bond equivalent (DBE) values of 1-27, containing N

“…Each of the four extracts (SFE1, SFE2, SFEN and DCME) was fractionated into saturates, aromatics, resins, and asphaltenes (SARA) fractions by the Chinese Standard Analytical Method for Petroleum and Natural Gas Industry: SY/T 5119-2008 [21].…”

“…N1O1 compounds are considered to be intermediates of N1 species biodegradation (Kim et al, 2005). Shi et al (2010a) suggested that the oxygen functional group in the N1O1 compounds is a hydroxyl rather than a cyclic ether group because such compounds are present in polar resin fractions rather than in non-polar aromatic hydrocarbon fractions. In maltene fraction of L-2, N1O1 compounds with DBE values of 10, 13 and 15 are predominant.…”

“…Fractionation of maltenes was carried out on a silica/alumina column chromatography. [43][44][45][46] An open glass column of 2 3 60 cm 2 were packed with neutral alumina (200-300 mesh) in its lower half and silica gel (200-300 mesh) in its upper half. Silica gel was washed with toluene/dichloromethane/methanol (1:1:3, v/v) mixture and then dried.…”
