Characterization and quantitative determination of aromatics, nitrogen, sulfur and trace metals in fuel and hydrocarbon samples

Inumula, Vamshi

Abstract Details

2013, Master of Science in Chemistry, Youngstown State University, Department of Chemistry.
High resolution two- dimensional gas chromatography time- of- flight mass spectrometry (GC x GC TOFMS), inductively coupled plasma mass spectrometry (ICP- MS) and trace nitrogen/ sulfur analysis methods are used to analyze the fuel and hydrocarbon liquid samples. The high resolution two- dimensional gas chromatography (GC x GC) along with one dimensional gas chromatography are used to separate the complex samples and to report the identification of separated components provided by time- of- flight mass spectrometer (TOFMS). Traces of elements in gasoline, diesel fuel, pygas samples are determined by inductively coupled plasma mass spectrometry (ICP- MS). A lithium metaborate fusion method was used for sample preparation. As nitrogen/ sulfur are present in smaller concentrations in gasoline, diesel fuel and pygas samples, accurate determination of these nitrogen/ sulfur concentrations is important for quality control, to prevent engine deposits and to meet the regulatory requirements. For this a nitrogen/ sulfur instrument with an automatic quick furnace is used for selective and sensitive measurements of these elements.
