“…16,17 To date there has been little investigation using GC×GC separations of the species formed via oxidative instability reactions. There has been some study of the role sulfur compounds play in thermal stability using GC×GC-TOFMS, 13 but the investigation of oxygenated species remains largely unreported.…”

Oxidation of aviation fuels prior to combustion affects the safe operation of high performance aircraft. This study reports the use of comprehensive two-dimensional gas chromatography (GC×GC) with accurate mass time-of-flight mass spectrometry (accTOFMS) to study oxidized species in complex thermally oxidized conventional and alternate aviation fuel matrixes. Tens of thousands of unique compounds were identified in the fuels, highlighting the need for comprehensive separations. GC×GC operation allowed a range of oxidized species to be isolated and identified, and in a conventional fuel, a series of homologous aldehydes and 2-ketones were found. 4-Methyl-2-hexanone and 1-pentanol were found to be strongly correlated with established methods for quantitatively assessing fuel stability.

“…It has been successfully applied in molecular characterization of complex mixtures, such as petroleum products [21,22], shale oil [20], bio-oils [23][24][25] and coal derivates [26][27][28]. Meanwhile, electrospray ionization (ESI), a soft ionization technique, can selectively ionize polar molecules.…”

“…Significant research possibilities still exist in this area and future investigations in characterizing chemicals in CDLs may mainly focus on the following respects: (1) developing other types of ionization techniques except ESI (e.g., APPI, APCI, LDI, MALDI, DART, etc.) for specific class chemicals in CDLs and comparing chemicals revealed by different ionization techniques in the same sample; (2) characterization of high‐molecular hydrocarbons and biomarkers; (3) revelation of nonvolatile and heavy carboxylic acids, especially aromatic acids, produced from coal mild oxidation with ESI FT‐ICR MS; (4) application of chemical derivatization approaches combined with FT‐ICR MS analysis for characterizing hydrocarbons and SCCs; (5) identifying chemicals in CDLs using FT‐ICR MS along with other analytical techniques as reported (Omais et al, ; Koolen et al, ).…”

Coal-derived liquids (CDLs) are primarily generated from pyrolysis, carbonization, gasification, direct liquefaction, low-temperature extraction, thermal dissolution, and mild oxidation. CDLs are important feedstocks for producing value-added chemicals and clean liquid fuels as well as high performance carbon materials. Accordingly, the compositional characterization of chemicals in CDLs at the molecular level with advanced analytical techniques is significant for the efficient utilization of CDLs. Although reviews on advancements have been rarely reported, great progress has been achieved in this area by using gas chromatography/mass spectrometry (GC/MS), two-dimensional GC-time of flight mass spectrometry (GC × GC-TOFMS), and Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS). This review focuses on characterizing hydrocarbon, oxygen-containing, nitrogen-containing, sulfur-containing, and halogen-containing chemicals in various CDLs with these three mass spectrometry techniques. Small molecular (< 500 u), volatile and semi-volatile, and less polar chemicals in CDLs have been identified with GC/MS and GC × GC-TOFMS. By equipped with two-dimensional GC, GC × GC-TOFMS can achieve a clearly chromatographic separation of complex chemicals in CDLs without prior fractionation, and thus can overcome the disadvantages of co-elution and serious peak overlap in GC/MS analysis, providing much more compositional information. With ultrahigh resolving power and mass accuracy, FT-ICR MS reveals a huge number of compositionally distinct compounds assigned to various chemical classes in CDLs. It shows excellent performance in resolving and characterizing higher-molecular, less volatile, and polar chemicals that cannot be detected by GC/MS and GC × GC-TOFMS. The application of GC × GC-TOFMS and FT-ICR MS to chemical characterization of CDLs is not as prevalent as that of petroleum and largely remains to be developed in many respects. © 2016 Wiley Periodicals, Inc.
