Analysis and Comparison of Nitrogen Compounds in Different Liquid Hydrocarbon Streams Derived from Petroleum and Coal

Abstract: Identification and quantification of nitrogen compounds in five typical liquid hydrocarbon streams, including straight run gas oil, light cycle oil, and ultralow sulfur diesel derived from petroleum and coal liquids from the coal pyrolysis and the direct coal liquefaction, have been conducted by a combination of the modified solid phase extraction and gas chromatography with a mass spectrometry detector (GC−MS) and a nitrogen/phosphorus detector (GC−NPD). A simple and efficient method was applied for preisolat… Show more

“…[7][8][9][10] To characterize volatile and thermo-stable analytes in the lower molecular mass range, gas chromatography coupled to mass spectrometry (GC/MS) [11] is the method of choice, especially two-dimensional gas chromatography coupled to MS (GCxGC/MS). GC/MS has been shown to be suitable for the analysis of hydrocarbons (aromatics and paraffins), [12] nitrogen compounds, [13] naphthenic acids, [14] and origin biomarkers. [15,16] Crude oil analysis by either ESI-FTICR-MS, APPI-FTICR-MS or GC(xGC)/MS(/MS) requires sample preparation ranging from a simple elution through a preparative chromatographic column separation to derivatization that could take up to 48 h to be completed.…”

“…Similar NCCs were found in the creosote and SRC‐II FOB from DCL by GC/MS combined with high‐resolution GC, and other NCCs like benzocarbazoles and dibenzocarbazoles were also detected (Wright, Later, & Wilson, ). A combination of modified solid phase extraction, GC/MS, and GC with nitrogen‐phosphorus detector was carried out to identify and quantify the NCCs in the liquid products from petroleum and coal (Li et al, ). The results show that a mild distillate (boiling point 196–380 °C) from DCL not only contains significantly different kinds of NCCs compared to liquids from petroleum but also has much higher nitrogen content.…”

“…[88] Thes eparation of nitrogencontainingc ompounds in liquids derivedf rom coal liquids and petroleum has also been studied. [89] Ap ossible application of these LCANs could be their hydrogenation to form fatty amines,w hich are widelyu sed as surfactants.T he hydrogenationr eaction of the LCANs could be performed once the fatty nitriles were separated or even on the whole Hep-sol fraction, since its subsequent separation from the samplewould not be difficult.…”
