“…Non-hydrocarbons mainly include nitrogen-containing compounds, sulfur-containing compounds, oxygen-containing compounds, and metal-containing organic compounds. The comprehensive characterization of hydrocarbons in petroleum has become a challenging problem because of the variety of compound types, wide distribution range of molecular weight, and large polarity difference [1][2][3]. Comprehensive characterization at the molecular level is the foundation of molecular refining to obtain high-quality…”

The progress in ultrahigh-resolution mass spectrometry (UHRMS) and related technologies has significantly promoted the development of petroleomics. The study of petroleomics has greatly broadened our knowledge of the composition of petroleum at the molecular level, especially heavy fractions that cannot be analyzed by gas chromatography (GC)-based methods. To date, heteroatom-containing (O, N, S, and metal atoms) compounds in petroleum have been studied extensively by UHRMS. Nevertheless, the main components of petroleum, hydrocarbon compounds, have remained out of reach of petroleomics characterization for a long time because they are too difficult to be softly and efficiently ionized for UHRMS analysis. It is undoubtedly the case that petroleum hydrocarbons should not be the missing part of petroleomics characterization since they play important roles not only as feeding pools for various high value-added petroleum products but also as critical biomarkers for geochemistry studies. Here, the most recent breakthroughs in petroleomics characterization of hydrocarbon compounds using UHRMS rather than conventional methods have been reviewed. Innovations of soft ionization methods can transform non-polar hydrocarbon molecules into molecular ions or quasi-molecular ions that are reachable for UHRMS without fragmentation. The development of data processing methods has assisted the decoding of the complicated UHRMS data to visualize the molecular composition and structure of hydrocarbon compounds. These advances make it possible to see the whole picture of petroleum compositions, from light distillation fractions to heavy distillation fractions, and from small volatile molecules to large non-volatile ones. The applications of UHRMS-based methods for petroleomics characterization of hydrocarbon compounds in crude oils and various petroleum samples including fuel oil, slurry, and even asphaltene have made a great contribution to petrochemistry and geochemistry studies, especially in the fields of molecular refining and biomarker discovery.

Carboxylic Acids in Petroleum: Separation, Analysis, and Geochemical Significance

et al. 2021

View full text Add to dashboard Cite

Carboxylic acids (CAs), common oxygen-containing compounds in petroleum samples, have been paid high attention in several areas, including petroleum geochemistry, petroleum processing, and petroleum pollution research. This paper focuses on the overview of separation and analysis of CAs in petroleum and its geochemical significance. The first section describes those studies that have aimed to separate and enrich CAs from the extremely complex petroleum samples prior to instrumental analysis. In the second section, the methods for identifying and quantifying CAs are discussed, in which massspectrometry-based methods are highlighted because of their superior performances in qualitative and quantitative analyses of individual CAs. The third section presents the studies on the geochemical expression of CAs in crude oils and hydrocarbon source rocks. This includes the investigations of CAs as molecular markers in research of the origin, migration, and biodegradation of oil.
