“…7c), the DBE distribution ranges from 1 to 20. It was verified that all the samples have a predominance of DBE 1 compounds (acyclic acids), which are mostly reported as fatty acids (Rocha et al 2019, Martins et al 2021 (Shi et al 2010, Liu et al 2015, Han et al 2018a. It is noticed once again that oils I and II have a different trend than Control Oil.…”

Biosurfactants and waterfl ooding have been widely reported thus far for enhancing oil production. Nevertheless, there is a lack of literature to explore enhanced oil recovered methods effects on its chemical composition. The aim of this work is to investigate the effects of a biosurfactant produced by Bacillus safensis and brine injection on the recovered petroleum composition, and their implications for geochemical interpretation. Original and oils recovered from displacement tests were analyzed by gas chromatography and ultra-high-resolution mass spectrometry, emphasizing saturated and aromatic biomarkers and basic and acidic polar compounds. Geochemical parameters based on some saturated compounds were subtly affected by the recovery methods, showing their reliable applicability in geochemical studies. Contrarily, parameters based on some aromatic compounds were more affected by biosurfactant fl ooding, mostly the low molecular weight compounds. Thus, these aromatic parameters should be applied with caution after such methods. The distribution of basic and acidic polar compounds can also be modifi ed affecting the geochemical interpretation. In the case of the basic ones, the biosurfactant greatly infl uenced the N class species with favorable loss of lower aromaticity compounds. In addition to water solubilization, the compositional changes described in this study can be related to fractionation due to adsorption on reservoir rocks.

“…Os componentes ácidos, especialmente os de cadeia longa, são os principais constituintes dos lipídios em organismos vivos, e sua presença em amostras geológicas pode ser associada a precursores planctônicos, bactérias, fitoplânctons e outros organismos marinhos (SCHAEFFER et al, 1993). Assim, considerando o potencial largamente inexplorado de ferramentas geoquímicas baseadas nesses compostos polares, muitos grupos de pesquisa têm intensificado estudos sobre ácidos presentes em amostras de origem geológica (NASCIMENTO et al, 1999;GALIMBERTI et al, 2000;KIM et al, 2005;VAZ, 2011;GRUBER et al, 2012;MARTINS et al, 2017b;MARTINS et al, 2021).…”

“…These parameters are based on the most readily degraded phenolic and/or benzylic O1 compounds by microorganisms and the persistence of O1 compounds with higher DBE values in more degraded oils. In a more recent paper, 113 the authors suggested some new paleoenvironmental proxies relevant to phenolic compounds for the application FT-ICR MS results: phenol index (% DBE 4; O1 class), C 27 /C 28 DBE 4 (O1 class), and C 27 /C 28 DBE 5 (O1 class). A higher value of the phenol index indicates higher land plant input during the black shale deposition.…”

Molecular Characterization of Fossil and Alternative Fuels Using Electrospray Ionization Fourier Transform Ion Cyclotron Resonance Mass Spectrometry: Recent Advances and Perspectives

et al. 2021

Molecular composition analysis of petroleum and alternative fuels has been considered as one of the greatest challenges in analytical chemistry. The rapid development of Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS) has provided an opportunity to solve this problem. High mass resolution power and mass accuracy enable the separation of isobaric compounds in a complex mixture and assignment of their molecular composition. The combination of electrospray ionization (ESI) with FT-ICR MS achieves direct analysis of polar compounds in petroleum even if they are in trace amounts in the complex matrix. FT-ICR MS has made a great contribution to the chemical understanding of petroleum and alternative fuels; the relevant application is sometimes called “petroleomic analysis”. Hundreds of journal articles have been published over the past two decades using FT-ICR MS instruments to study the molecular composition of petroleum and alternative fuels, in which most of them used ESI as the ionization source. This review will present an overview of the studies regarding the petroleomic characterization of fossil and alternative fuels by FT-ICR MS coupled with ESI and a critical review of their main findings relevant to the chemical composition. Special features of this review are (1) covering the entire historical period; (2) focusing on ESI ionization; (3) a systematic review of the composition of almost all the components and compound classes, including but not limited to petroleum, coal-derived liquids, biofuels, and their distillates; asphaltenes, heavy residues, interfacial active substances; hydrocarbons and heteroatoms; and polar and nonpolar compounds. In addition, the challenges and further research directions will be proposed. This review focuses on the advances enabled by ultrahigh resolving power FT-ICR MS in a tribute to Professor Alan G. Marshall.
