Orthogonal Selectivity for Separation of Oxygenated Compounds and Hydrocarbons in Alternative Fuels by Two-Dimensional Gas Chromatography using Zebron™ ZB-1701 and ZB-1 GC Columns; TN-2087

Abstract:

The need to diversify energy sources in the transportation industry has sparked great interest in direct coal liquefaction products. When they are first processed, the properties and composition for these alternative fuel source liquids are far from a traditional petroleum fuel’s final specification and therefore upgrading must be applied with the addition of gas oil cuts. In fact, the alternative fuel composition consists mainly of aromatic hydrocarbons, cyclic alkanes (naphthenes), heteroatomic compounds, and especially oxygenated species [1-4]. To plan for the refining of the alternative fuel source liquids with their additional petroleum cuts, it is crucial to first analyze their chemical and physical properties. Multidimensional gas chromatography is the perfect analytical technique for this challenge. The analysis results obtained using Zebron® ZB-1701™ and ZB-1™ GC columns together enabled the GC×GC-FID system to unravel molecular structures of oxygenated compounds in a coal-derived middle distillate.
