“…GC‐TOFMS analysis detects only a few OCCs in the naphtha, such as ketones, alcohols, and phenols, while GC × GC‐TOFMS (column configuration: Solgelwax × DB‐1) reveals more than a hundred OCCs in the naphtha and the OCCs can be classified into phenols, alcohols (alkanols and cycloalkanols), furans, ketones (alkanones and cycloalkanones), and carboxylic acids. Phenols and furans are similar to those reported in the middle distillate (Omais et al, ). Most of the ketones and carboxylic acids are revealed for the first time in DCL products.…”

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.

“…When integrated with time-of-flight mass spectrometry (GC Â GC/TOFMS), it is one of the most effective methods for separating complex mixtures [6][7][8][9][10]. This technique is useful because it offers a large amount of information that is difficult to obtain by conventional one-dimensional GC [11][12][13][14][15].…”

“…This technique is useful because it offers a large amount of information that is difficult to obtain by conventional one-dimensional GC [11][12][13][14][15]. For the best separation of crude oils and highest resolution of oil geochemistry, researchers have devoting to testing different analytical conditions, such as column lengths, modulation periods, and oven conditions [2,10,[16][17][18]. For example, in a detailed analysis of the oxygenated compounds in a coal liquefaction product, Omais et al tested and compared different analytical conditions involving innovative column configurations, and found the best one that enable an outstanding separation for the oxygenated compounds [10].…”

The work describes the application of columns with high-polar stationary liquid phases based on pyridinium ionic liquids for GC × GC separation of bio-oil and product of coal pyrolysis. By using inverse combination columns-the first ionic liquid column, the second is HP-5 the good separation results have been obtained. In the analysis of coal pyrolysis products, the suggested approach provides a much better resolution between components in comparison with a less polar first-dimension column (ZB-WAX). The good selectivity for peaks of phenols is observed, and the group of phenols is well detached and separated from the group of diaromatics. For bio-oil also good separation picture was obtained, the groups of phenols and guaiacol derivatives are distinguished with good resolution of substances within each group.
